Is anyone making money with these "Like" external websites?

Seem to be plenty of these popping up on facebook, and for some reason they seem to be vastly more popular/more liked than actual fan pages.

Is anyone here making any money from them?

anyone, pls share some of your experience

Yes, people are definitely making money with these pages. However, I doubt you are going to find anyone that is going to openly share what they are doing and how they are doing it.

Read this forum (especially the FB section) and research FB's Open Graph API.
