Facebook is similar liked friendster if you happened to use it. Its liked online community place where you can find your friends and even long-lost-friends. Post up your recent activity pictures so that your friends can view them. Facebook made it more interesting by giving user the freedom to install application on their own account; liked games, online books, interactive windows to chat with friends or maybe strangers you never talk before. Its liked a virtual mini world in there. Can be as fantasy as you can imagine or as real as real world if you picture it.
One application attracts me and i done a small picture of carbuncle. Here is it.
