Well, I don't know exactly how to use this site, but I am getting pretty excited about it anyway. Netvibes is an all inclusive search plus widget dashboard. If you notice to your right, I am a little bit of a widget lover...just a bit. This site give a great tour and has a wizard to get you started. For instance, above you see my "First Grade Finds" dashboard. I typed "first grade" in the search field and in a couple seconds the site found me tweets, images, discussion, you name it. And then you have options to share and play.
This is fun and hopefully worth my time!
