The 2007 Edublog Award finalists have been announced, and the list (with descriptions) can be found here. As we might have hoped, Classroom 2.0 is one of the finalists in the category of "best educational use of a social networking service." :) The list of all the nominees is well worth reviewing.
The final awards are tabulated from the voting which anyone can do by clicking through the individual categories. The link for voting for social networking is here. Because the winner is tabulated from the votes, I almost feel sheepish encouraging voting for CR 2.0, since the other sites are most worthy, but don't have nearly the membership that we do.
On the other hand, CR 2.0 exists to help introduce the tools of Web 2.0 and social networking to educators, and winning would be a good way to continue the exposure to the tremendous resource of all those who contribute here. So, I say, vote!
