Bloggiesta is awesome! It's hosted by Suey from It's All About Books and Danielle from There's A Book.
During Bloggiesta you get to:
Meet other bloggers. No time or money to attend conferences? Bloggiesta is free and comes right to you!
Work on your blog. Is that Review Archive updated? Captcha turned off? Do you know what SEO stands for? Do the letters HTML make you break out in hives? Have you backed up your blog recently? Oops -- ever? Bloggiesta inspires you to get started on some blogkeeping!
Win cool prizes. There are lots of mini-challenges, many of them with prizes. I'm hosting a challenge. With a prize!
