"BlogCatalog is more than just a social community for bloggers; we are one of the largest blog directories on the internet. Whether you are looking to search blogs, connect with bloggers, learn more about blogging, or promote your own blog, BlogCatalog is for you!" [Blogcatalog]
It's funny as soon as I started an account on Blog Catalog which is a social community. I did it, to get some traffic to my site, which I have done! Plus I have met some really nice people! A win-win situation!
