Afrigator. (Note the funky "I am an African Blogger" button on my blog. It's at right, just below the atheist "A").
Afrigator is a bit like Technorati for African bloggers, but it has a bunch of other cool features. Like Technorati, Afrigator ranks the top African blogs, counts the number of links between registered blogs ("Gator Love"), and aggregates posts, highlighting important stories. Afrigator also serves as a RSS reader and a traffic counter to boot. Check out my blog's public listing (I'm 367th in South Africa and 566th in Africa... Hooray).
If you're an African blogger, I certainly recommend joining.
