I've been using Netvibes for awhile now, but I didn't realize until I read this post on TechCrunch, as to just how cool it's turning out to be. Tabs are definitely cool, I was pretty excited about those for awhile, especially since that was my favorite feature on Pageflakes, but I wasn't compelled enough to switch over to that site. You can now add icons to tabs and create your own modules using Netvibes APIs and other APIs available. Netvibes has also created a developer site called Netvibes Ecosystem that allows developers to contribute their creations to the Netvibes community.
I admit that I haven't been using Netvibes that much lately. I found it good for taking notes and organizing some things but the whole start page thing kinda went dead when I enabled Session Manager on my Tab Mix Plus options. Now when I close my browser in the middle of something I know that it'll be there when I open it again. I realize that this behavior only encourages me to start many things that I'll get to later and clutters up my browser in the process...but as I've found out about myself, if I don't see it I don't do it. My need for organization and tabs in Netvibes would encourage me to hide things in the start page tabs and I won't see those when I open my browser...it's a personal dilemma that I will learn to deal with (maybe). Netvibes is still cool, and it is one of the many browser tabs that do open when I open Firefox.
