Last weekend, I helped launched the temporary “save the date” site for the Los Angeles chapter of the 2010 Twitter festival — Twestival.

Twestival is an annual charity celebration, which takes place in hundreds of cities around the world, brings together thousands of Twitter users offline to rally for an important cause.

If you’re in the L.A. area on Thursday March 25, 2010, join us. If not, see if there’s a Twestival in your neck of the woods.
