This is more a blogger resource than a librarian resource, but it was started in KidLitosphere, so that should count for something.
Bloggiesta! is held in January (this weekend, in fact) for bloggers to help set the pace (especially for those who made it a resolution to blog more) for blogging through the new year. There are mini-challenges* for bloggers to complete that will help decide the direction you want your blog to go in, with brainstorming in general.
*Those who keep track of their progress will be eligible for giveaways.
The mascot of Bloggiesta! is Pedro, which stands for Plan, Edit, Develop, Review, Organize.
To sign up, find out about the mini-challenges, or for more information about Bloggiesta!, go here.
