I've used google docs a couple of times now, for group projects, and it's a pretty good tool. I can't say it's got the best tools for typesetting and graphics, but it does make things easier to collaborate on. That was particularly good for an online class that included several group projects. The down side is that it is sometimes hard to tell if everyone has actually looked at a piece, even if they have not edited it. I guess that's an issue that's more about communication than anything else.
The web 2.o award-winning sites were okay. The education category was a bit disappointing, though, because I thought it would be more related to the world of education, rather than things that can educate users. I guess that's an assumption I make coming from the world of educators. A number of innovative sites, but only some were really useful. It was good to see that the most visible employment sites (monster and career builder) are also winners, too, in the event I have to use them.
