I'm pretty sure he's still here, just under a different name. I don't want to say what I think the new user name is because I'm pretty sure he did what he did to try and get some anonymity and not have to deal with people hounding him for stuff. Can't exactly blame the guy for that.
And, as much as I love GH, I totally understand why he might need a break from it too.
Looks like Hipster decided to rebrand and start something new. His style is unmistakable though
Doesn't hurt that the picture on the back of the cap was his avatar for a while too.
