Here are the steps:
- Subscribe to the feed of your favorite blog with Google Reader
- In Google Reader, go to the Settings option that's on the top menu on the right
- In the Settings page, in the first tab Preferences, select your native language from the Language combo box.
- Click on the "Back to Google Reader" link to view the blogs you have subscribed to.
- If you have subscribed to multiple blog feeds, select a single blog Subscription from the Subscriptions panel on the left.
- In the detailed listing of Feeds in the main panel, click the "Feed Settings..." drop down that is in the section below the blog title.
- From the drop down list, choose "Translate into my language." (if you have changed your language in step 3 to a non-English language, you would see the message "Translate into my language." & all other labels in Google Reader in your native language)
- Voila! Now all the posts will appear in your native language.
