On Saturday, July 30th, numerous bloggers will brave sleep deprivation, over-caffeination, and goggle-eyes with one collective goal in mind: raising money for their favorite charities via Blogathon 2007 by posting to their blogs at least once every 30 minutes for 24 hours straight.

The Blogathon has raised hundreds of thousands of dollars altogether since it's inception in 2001 and is still going strong with even more bloggers and sponsors pitching in each year.

From the official event website:
"What is a blogathon? ...remember when you were in school and you would bowl for charity? And for every pin you knocked down you got, say, ten cents? Or run for a dollar a mile? During the Blogathon, people update their websites every 30 minutes for 24 hours straight. For this, they collect sponsorships. Pledges can be a flat donation, or a certain amount for every hour the blogger manages to stay awake."

There's still time to sign up as a blogger, a sponsor, or a monitor - or for more information check out the event FAQ.
