Interesting note, Jack Osbourne actually mentioned Friendster on Kimmel last night. Guess it really is catching on. My biggest problem with Friendster right now is its extreme growing pains. The other day, I was trying to approve a new friend and had to log in about seven times before I could even get to the page, got temporarily unavailable notices two or three time, got Document Contains No Data about three other times. Not a very friendly web experience. Hopefully they can get past these growing pains and actually start having a service that is worth something.
Eventually I can see them adding new features too, like IM groups and whatnot, but I really think they need to stabilize the current product before they do anything else.
