I don't actually think it's possible to know who exactly has viewed your profile... only a location on a map that is very inaccurate. There is a site that shows you who has removed you and recently added you. I find that useful in some cases.
I heard there are some applications by using that we can track...... but i exactly dnt knw from where i get these applications....
Hey if anybody knows any trick I would also like to use such an application...so that I'll come to know how famous I am...
