While I'm not a big fan of Google, it has the only translation service outside of BabelFish that a lot of people use. Since I'm not bilingual (or multi-lingual, or any lingual besides English) I don't know how well Google Translate works (or how accurate its translations are) but more than a few people use it over on the other blog, which brings me no end of joy.
In the last month I've seen readers translate multiple pages per session into Japanese, Chinese, French, and Russian. When the Google Translate visitors show up in my stats I always click through to the pages they visited to see how they look in different languages. They look wild in Asian character sets and pretty nifty in Russian. It's one of those things that just grabs me - like watching my blog go international without any of the drama that that statement would seem to imply.
