Who needs a walk-a-thon when you can join a Blogathon!

Starting Saturday, July 28th at 6 AM PST, 2007 Blogathon bloggers will post a new post every 30 minutes for 24 hours to raise money for their favorite cause. As of this writing, 240 bloggers have registered for the Blogathon and $16,161.91 in pledges have been made.

For bloggers with other commitments, such as religious observances, that cannot be rescheduled, there will be a B-Schedule which will begin at 9 PM PST on Saturday, July 28th and will continue until 9pm the following night.

Unfortunately, the Blogathon coincides with the BlogHer Conference again, so I won't be joining this year, but if you'll be blogging, check out Lorelle Van Fossen's fantastic Blogathon Tips like:

• Choose a charity people can identify with
• Give readers a reason to donate
• Blog to more than your fans:
• Plan for 48 blog posts

Nancy's Baby Names

will be blogging for First Book and is encouraging her readers to pledge any amount, "For instance, just $5.00 — not much more than the price of a Starbucks Frappuccino — will buy two books for a child. (See? You can lose weight and bolster literacy at the same time!)"

JilBean will be blogging for the National Multiple Sclerosis Society, Greater Connecticut Chapter. As of July 8th she had already raised $297 in pledges towards her $900 goal.

Lone Prairie will be blogging for the Joni and Friends International Disability Center. She will be posting drawings each half hour.

Tish and Mike of The Kat House and Ordinary Folk will be blogging on Blogs We Luv for The Glaucoma Foundation. For each $5 you donate you will receive one entry to win a $25 Amazon Gift Card.
