Before WordPress, there was a lot of discussion about what code language to use to write your own blog. Looking back on it now, it seems quaint. Many website developers thought the XML language would win out for blogging (AND replace HTML4). Others thought Atom would prevail. But that's not what happened.

So there's no longer any need for a separate blog search engine to find a particular blog; Google will do nicely.
