Check out the Linguablogs web ring if you're interested in language. Right there are links to ten or so interesting blogs, at least for us linguists, teachers, translators, and the like. We get the idea that these guys are sort of their own little blog ghetto, as we'd never seen any linguistics sites before and suddenly came across not one but a lot. We're not sure if we count as a linguistics blog, but we do seem to find ourselves talking about language a lot.
