Sounds great nicolagreco, I’ve seen this feature being used in quite a few communities and personally I think it’s cool to see if/who is actually looking at your profile and maybe even come back because they find your profile interesting. Its just another activity widget which is nice-to-have in my opinion.
A lot of our ipb forum users love this sort of information because they always tend to visit the user profiles who visited their profile. So the profiles are pretty active and that’s what social networking is about. ^^
