Today is the last day to vote in NetSquared's "Mashup Challenge". There are 122 projects in the running, all of which merge data in new and interesting ways to work towards social change.

You have to vote for at least five and no more than ten projects.  To get you started, take a look at my three favorites: Mapping the Media Change Movement by the fabulous folks at the Media and Democracy Coalition, My Polling Place, and MAPLight.org: Mapping Money and Politics. 

If you think these or any of the other projects on the NetSquared site are worthy of winning $100,000, go vote before 5pm pacific time today!  The voting process is a tad complicated, but I know the nonprofits that are competing for the prize money will appreciate you taking the time to help them out.
