Have you heard of the The Blog Guidebook?
If not, you must go there now!
They're a great resource for blogging with tons of tips and resources for blogging and you can have your blog listed in the guidebook and search for other blogs by category!
Last year they had a calendar for 2011 available for download, that I LOVED and this year, they've done it again! It is so pretty! You can either download it or order a printed copy.
