SITE REVIEW: Whosend.com

k.. so you organize each area and so that only posts in that area are posted in that area only ? which if you post on a wall in a area on facebook that is only for that area ? again am I missing something ? of course in facebook if you post your status update then you everyone that you are "friends" with gets to see that..

yes each area(followable) has its own entry space (photo albums, video albums, files, activities etc...)

from the area I mean a shared space between a subset of your friends.
there is only one followable some of the friends can write others just follow.

I have updated intro page to make more informative, any suggestions?

Its a nice site but I want to give you a humble advice i.e you have used so many tables in your site which are just slowing down it a bit. Try to use more div which will surely decrease the loading time
