The Blog Guidebook is a great resource for all things bloggy ~ you can search blogs by topic, list your giveaways (and see others!), and find and list those linky parties we all love so much! They also have general blogging tips and resources for blog design (they're really G-O-O-D!) This is a "must-be-a-follower-of-this-blog" blog. You know what I mean.
BONUS: Aaaaaaaaaaand if you head over there TODAY I know you'll be pleasantly surprised by their most recent generous offer. So stop over there, list your blog in the directory and let the fun begin!
