Now you can read blogs of your favorite topic regardless of the language they are written in as Google Reader now provides you with an option to translate the feed content into language of your choice.
It uses Google Translate service to do translation and therefore those languages will be available which Google Translate understands.
Next time you find an interesting feed in another language, just subscribe it in Google Reader as you always do and click on Feed Settings and then on Translate into my language. You can adjust your language in Google Reader Settings page.
Google Reader remembers your choice of translating the feed, so that next time you open that feed in Google Reader, you don’t have to choose Translate from Feed Settings.
