Is there a way for you to know who's looking at your profile in Facebook?

I was thinking about it before as well. I like the feature that Friendster has - we can see what other people has view our profile butI doubt Facebook has this feature, may be later they will add it.

Hello friend, In facebook we don't have any such application till now, which tells you how many or who all have seen your profile. There is a scam application which claims to tell you all this but please steer clear of that, as it is not going to do you any good and it will just take away your profile information.

I don't know if there's a way you can find out who viewed your profile, but I may be mistaken. I think you can know who viewed you profile when you receive a friendship request or something. If it bothers you who can view your profile you can lock your credentials only to friends. Why don't you ask Facebook support?
