Ok. You people have tried twitter. Its a social networking site where people follow your updates. Your updates is something no longer than 140 characters.
Phandy is exactly like twitter. The looks match that of twitter. But here, instead of lines of words, you use pictures. And the question "What are you doing?" is "What are you seeing?" here in Phandy. Update your favourite picture and people following you will get to see that. An ultimately good site for photographers and wallpaper-seekers. Try it!
