I won't be...

Now, 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.
