I think that Twitter's friends would only be celebrities who hire other people to talk to him, and pompous bloggers.
Also, xkcd would be somebody who used to be really cool and popular without really knowing it until he/she realized it and then turned into a massive ******bag.
Something Awful would be a young man, about 20 years old, with a temp job, who makes a very big deal about passing himself off as very unfriendly and "cynical", but generally fails since he's actually a pretty cool guy. Of course moments of genuine weirdness occasionally seep through and creep people out on occasion.
Zombo.com would be the coolest person ever that everyone always wants to hang with because he's so cool.
