Yes we all want to know who is visiting our profile pages, however don’t yet fall for that trap in the form of Twitviewer which claims to show you which users have visited your twitter profile.

Twitter has already sent out a notice to users to change their passwords if they have used that service.

To add to that advisory we also would like to say that, DO NOT use twitter services that ask for your username and password, twitter has a very easy to use OAuth API which can easily allow you to use any application without sharing your passwords.
