I do like Facebook, while I'm not on it as much as I used to be, I still try to check it once a day. My profile has got a bit out of control though. I've been adding a lot of friends lately too, mostly awesome librarians, but I realized that compared to my other networks, Facebook is probably my most diverse. I have old school friends, new school friends, people I meet at conferences, people I meet online... the personal/professional lines are criss-crossing on Facebook more than any place else. I'm ok with adding professional friends on Facebook, but it puts more pressure on me to make sure I'm managing my online profiles a little more effectively.
The biggest reason why I like Facebook as opposed to all other social networks so far is that I get more control over who sees what on this network. Given the nature of my network, this seems necessary too. Of course, I also co-wrote a paper on privacy in Facebook this past semester so I'm well aware of just how granular Facebook's privacy settings are. I think it's an often overlooked benefit of Facebook. I know most don't care about the specific privacy features on the site, that's fine, some people do and I think it's nice to have those options available. My personal thoughts on privacy are that each person needs to manage their identities to the point where they feel comfortable. I'm still trying to find that balance for myself, but the specific thoughts I have on privacy online are probably best kept for another blog post.
There are some people that use Facebook as their main starting point for everything, I don't. I use GMail, Twitter, Google Calendar, Google Reader, Del.icio.us, and a whole slew of other services that I have instead. I like that I can put some of these services into Facebook using apps. For me Facebook is just another place to aggregate things about me. Yesterday I went through my applications and added a few that seemed useful, while deleting a whole lot of junk I've been collecting on the profile over time. I also changed some privacy settings with the apps (yes you can control specific privacy settings with certain apps, it can be tedious but quite useful if you're concerned about privacy). Also, this article from ReadWriteWeb about making Facebook useful had some good suggestions for apps, I did use it as a guide as I went.
Events
I use Facebook more for discovering events rather than managing all of them there. Facebook's Events application is of course necessary, especially if you want to keep up on your friends' birthdays. The Upcoming Application adds events that you are watching or attending through your Upcoming.org account to your profile. I recently discovered an application called fbCal which allows you to view your friends' birthdays (and another link for upcoming events) in Google Calendar (or preferred calendar). This is great application for freeing you from the burden of checking your Facebook profile everyday.
Professional Profiles
The nice thing about some of the privacy settings in Facebook now is that you can control how professional your profile appears to some of your contacts. It does take some planning and a little bit of forethought when you add new apps to your profile (all apps are automatically defaulted to all of your networks and friends), but I don't think people have to be excluded from a network list just because someone thinks it "isn't professional enough". The Professional Profile Application makes it easy to include your resume on your Facebook profile, and if you already have a LinkedIn profile it's even easier, it just pulls your resume from there. The Business Cards Application allows you to create a tagline and attach a business card to your profile. If you use Facebook to contact people professionally it can be attached to messages as a sort of signature.
Sharing Files
Box.net's Files Application allows users to share files with one another. I personally like Box.net and I do use it on occasion, but my new favorite file sharing tool is Drop.io, I would love to see a Facebook application for this one instead.
School
The ReadWriteWeb article mentioned the Blackboard Sync Application... well as much as I loathe Blackboard, this one seemed useful, except for this nice message when I tried to add it: "Your Blackboard system administrator has blocked access to Blackboard Sync for Facebook." Good one WSU...
One feature I miss from old school Facebook is the ability to add my classes to my profile. The Courses 2.0 Application fills in that gap. If some of your other classmates are also using this application you can connect with them on there, as well as manage your class schedule.
To Dos and Calendars
There are quite a few applications to manage your to do lists and calendars, but like I already mentioned, I don't prefer to manage my life through Facebook. I use external sites like my GMail, I Want Sandy, Twitter, and Google Calendar for personal productivity, but if you're somebody who does like to use Facebook like this, there are quite a few apps available for you.
Social Networks
Facebook started adding support to import outside social networking sites into your news feed. I do prefer these to applications. The reason why is because I do have problems with buggy applications killing my internet connection. I also like simplicity. Currently I'm importing my blog as Notes, Flickr, del.icio.us links, shared items on Google Reader, and favorite songs on Last.fm.
If you're on Twitter and/or FriendFeed, there are also a couple of applications available to put those services on your profile. The Twitter Application will let you update your Facebook status with your tweets, this never really appealed to me though. My new favorite site seems to be FriendFeed, the FriendFeed Application is decent. There are lots of things going to there that are ending up on my FB profile too (like Twitter and del.icio.us), I like it on one hand, but I also wish I could avoid some of the duplication. The profile app gets a little long too so I've put it in the extended part of my profile.
I'm playing around with a lot of location based services lately, but Dopplr is my favorite so far. The Dopplr Application is definitely included in my profile, I'll decide if I'll be adding more later.
I like Skype, I would like to use it more so I added the Call Me on Skype Application. I haven't advertised my Skype presence much. It is one of the tools I have considered using for virtual ASIS&T meetings next year.
The As Seen On Application links my profiles from other sites. I basically copied what was already on my blog... those things are hard to keep track of when you're using so many different sites. I think I've resorted to only including the sticky ones.
Music
I went a little overboard with the music apps before, and I think these are the ones that were killing my profile. I've limited myself to three different ones. I've added the Last.fm Music Application, the Music Application (this is a Rhapsody app), and I kept TuneSocial because I've been saving my CD collection to that. The compatibility features of the Last.fm application seem especially cool. I have the Rhapsody application added because I'm a subscriber, but I do feel that Rhapsody constantly fails with social stuff and keeping their stuff locked up tight behind closed doors. I mostly listen to music through Rhapsody though so it's something I'm pretty tied to.
Books
I do keep track of the books I'm reading through the Books iRead Application. I think if I can get my data exported to GoodReads or LibraryThing easily, I might switch to one of those other ones instead. It's really helpful for me to keep track of books I want to read, sometimes I forget.
Movies
I'm not a big movie person, I used to have the Movies Application installed, and it's pretty good if you like movies, but I'm also a Netflix user so I really don't think to go on there and rate movies. I also work in a library so knowing what movies are new or coming out is never an issue with me... whether we like it or not, librarians are constantly getting recommendations from patrons on books and movies. I have installed the Netflix Movies Application, it shows the movies I have at home as well as what's in my queue (which I have to admit is a little scary right now, I should really clean that up). The application on the profile is a bit bulky though, I've put it in the extended part of my profile. Although with Netflix I'm going down to one movie a month because I just haven't been watching a lot lately. I really don't want to cancel my account though, I love Netflix!
People
Funny thing about this RRW post, it says to find people using Spock's people search app... sorry, that just ain't happening. I don't use Facebook much to find people, people usually find me ok.
Fun Things
I like the Friend Wheel friend visualization, also newly discovered Nexus Application for sorting through friend connections.
Fun Cards is installed but profile disabled. I just like sending birthday cards on people's birthdays!
Geocaching Stats add a widget to my profile with my current count of geocaching finds.
Memorable Web Address for Profile is just a simple application that makes your Facebook profile URL a little cleaner and shorter.
The Where Is It Application is profile disabled, but this is a nice one for attaching maps to messages or wall posts.
Of course you can't forget the xkcd Feed Application. Every Facebook profile needs a little funny.
Might Use More
I found that I installed the Extended Info Application and never used it. It looks a little involved, but it could be a great way to customize my profile a little more in depth.
Apparently you can send video using Facebook Mobile using the Video Application? I can shoot video on my sucky phone... although not sure if this is something I am interested in trying out.
Why Not?
Gifts, why not, it's a Facebook thing.
The Photos Application isn't one I use much, but when I take pictures of people that are taggable on Facebook I like to include those pictures there. Using Flickr kind of makes the Photos app unnecessary for me.
Groups, I join them, but they're not as useful or interesting as Pages. I think groups are more of an identity thing. But Pages do rock!
Posted Items is a another Facebook thing, I don't use it much, other than to post things about Facebook.
SuperPoke is currently profile disabled, but it's probably the only completely meaningless and annoying application I still have installed.
Settings
There are lot of different privacy settings and friend management features I still want to go through. Some people don't like to "categorize" their friends, but for me it's really a way to keep track of how I know a person. This is especially important if you meet a lot of people online or a few times every year at conferences.
Now the challenge for me is to keep from adding more stupid applications to my profile here on out.
