Lifehacks: Switching to Google Reader from NetNewsWireLite

I like RSS feeds since with the help of feeds and readers I can see the updated contents of hundreds of website on one surface. Now I’ve completed my desertion to Google Reader as my new basic feedreader from NetNewsWireLite. In order to import your subsriptions from NetNews you have to export it in an OPML format and upload it to Google Reader. From now on I can reach all my feeds with a new tab in Firefox. (I don’t understand why the Reader is unable to recognize the duplicate feeds.)
