At last I've been able to finish reading and moving all my RSS feeds from RSS Bandit to Google Reader.
It is a mere change to forget about reinstalling or keeping synchronized my feeds if some day I want to read them outside my laptop. Now I can read them everywhere without any problem, without having to export them and re-import after a PC reinstall.
Also, now I can share my rss (at least the tech. related ones) with anyone. On the left menu you'll find the "Feeds I Read" section, which contains not only the XML RSS feeds but even URLs to see them at google reader without even registering.
RSS Bandit is an excellent tool. I've been using it for quite a lot of months (a year at least), and the change is merely due to laziness and accessibility.
