Blog Catalog is also a place where people can keep track of your activity on sites like Digg, Flickr, Stumbled Upon, Delicious, Reddit, Technorati, Magnolia and MyBlogLog through an "Activity Feed". This is a great way for all your fans to keep track of your activity on multiple sites! Just add in your user names into your profile and Blog Catalog takes care of the rest.
Unlike MyBlogLog, Blog Catalog is completely independent, MyBlogLog is now owned by Yahoo. This tends to make the site a bit more community oriented with a lot less spam. Personally, I like it a lot more than MyBlogLog, but that is just my personal opinion. Not too mention, I have seen a lot more traffic in Google Analytics coming in through Blog Catalog!
Blog Catalog also has widgets that you can embed on your website to keep track of recent visitors, new members of your neighborhood (website), and even a recent discussions widget which will help you keep track of all that is going on in the Blog Catalog community. You can see an example on the sidebar of this page under "Blog Catalog Fans".
So if you are looking for more traffic to your site and a feeling of community look no further that Blog Catalog! You can sign up here or check out my profile here, don't forget to sign up for all my communities when you get a chance. I know there is a lot, but what can I say : )
