You cannot find out how many people view your profile.
It’s been designed to appeal to our most basic, narcissistic instincts — a Facebook application that lets you know how many people have looked at your profile. Another promises to remind you of what your first status update was.
The number of users posting updates from these applications is only rivaled by the number of their well-meaning friends posting alerts that the whole thing’s a scam, designed to steal your personal information.
While equally annoying, these friends are actually onto something. Technically, these apps aren’t stealing anything that you’re not already publishing, but neither application tells you exactly what it’s going to do with the information — and it’ll access just about everything you’ve ever even thought about putting in your profile.
