DonorsChoose Blogger Challenge 2008: more ScienceBloggers roll out challenges.

We're in day 2 of our month-long drive to fund projects in public school classrooms across the U.S. As I write this post, the generous readers of ScienceBloggers have given a total of $5,589. And, since yesterday, challenges have been mounted by:

Dispatches from the Culture Wars (challenge here)
Signout (challenge here)
The World's Fair (challenge here)
Zooillogix (challenge here)

Check out the ScienceBlog leaderboard to follow our progress. And thanks for being such a generous bunch of blog readers!
