Technorati calls itself the authority on what’s going on in the world of weblogs. Be that as it may, I use it quite frequently to search for differing topics if Google doesn’t come up with what I’m looking for.

A feature I’ve been using more recently, is Technorati’s ability to feed me posts which are tagged with a certain keyword. Just add the URL to your feed reader, exchanging google for whatever tag you are interested in.

Apropos Technorati tags: see also an introduction to Technorati Tags.
