Happy TweetsGiving

For some do-gooders, today isn’t just Thanksgiving. It’s also the second annual TweetsGiving, the culmination of a 48-hour global effort to raise money online for a school in Arusha, Tanzania.

Participants are encouraged to share what they are grateful for – and donate money, of course - through Facebook, Flickr, YouTube, and of course, 2009’s new media darling, Twitter.

The project is the brainchild of a U.S. nonprofit called Epic Change. Last November, Epic Change’s efforts raised $11,000 in 48 hours through hundreds of small donations, which the organization used to help build a classroom at the Tanzania school. Epic Change dubbed the students the “Twitter kids of Tanzania” and encouraged users to send tweets to them via their #Twitterkids blog.

This year, Epic Change had hoped to raise $100,000 by midday Thanksgiving to build the school a dormitory, library, cafeteria and more classrooms. As of Thursday at 11 a.m. ET, however, the effort had raised only about $26,000 – a possible victim of the worldwide recession.

If you still want to donate, however, it's not too late.
