I miss doing the bloggiesta blogathon that Maw Books ran so I created a blogathon Mar 9-11 along the same lines. It's not just for book blogs, any blogger is welcome. The more the merrier.
Get your blogging to do list done. Participate as much as you can. Participate for free, be eligible for prizes, get blogging how to information and have fun!
