I've got a pretty extensive list of blogs that my aggregator (now Google Reader) pulls down. I will see roughly 500-700 posts a day (not that I read them all). However, for the last year or so I'm seeing a lot of foreign (to me) language posts that make up a good bit of those numbers. I really wish that there was a way to filter out posts that are not written in languages you are interested in (similar though here).
Does anyone know of a way to accomplish this without it being a feature of your aggregator?
