Global Youth Service Day will be brought to you in live Twitter form with event updates (and locations, to broadcast on TwitterVision.com) throughout the day.
I'm using Swotter to push out the events we have in our Google Spreadsheet (exported to a more SMS-length-friendly format), which is also driving our GYSD-US Map (warning: VERY resource heavy Simile/Exhibit Map Mashup). I love technology that likes to talk together!
It's pushing the events straight through the API, and then a combination of TweetScan and TwitterFeeds are retweeting any #gysd tagged tweets, which was my original gysd/twitter plan
So... we'll see how it goes...
