Yes I know all my stats on facebook like who visits my profile the most, who comments me most, who visits me most/least and many things like that, that you wished you knew.
This facebook application made it easy to find me the friends who are closest to me (except on the real life) on facebook.
Just been a week since I knew it.
Arrgh! So many applications. I will get through more like these in coming days.
