If you want to translate foreign news sites or blogs, you usually have to do it manually with a service like Google Translate. However, tech blog Digital Inspiration shows off how to use Google Translate to automatically translate RSS feeds and send them to your favourite reader.
If you exclusively use Google Reader, you can change your settings to automatically translate pages. However, if you use third-party apps like Flipboard, Reeder or Feedly, the process isn't automatic. Digital Inspiration's method uses a Google Script to translate the site and then creates a RSS feed URL you can plug into your favourite reader. You only have to do it once for each foreign language site you want. Head over to Digital Inspiration for the full guide.
