Worldchains - An Alternative to Facebook?

A new website called Worldchains has recently been made (after the controversy of Everyone Draw Muhammad Day) by a Pakistani. Even though I just signed up, it seems almost an exact copy of Facebook and might prove to be very successful especially if Facebook is banned in Pakistan forever. However, of course there will be some setbacks of using this, at least in the beginning, because all the contacts that a person could have might not be willing to sign up at this site. It has got a few extra options which might be annoying to many and some options just don't work properly while I can't figure out how to do some of the same stuff which I used to on Facebook but on the whole, it's not bad. Following are the details of this site.
