Man, i'm 19, and i can't read what 13 years old write in their chat language.

But yea, this really does remind me of L33t
but i never saw any one use pure L33t for a web site when it was more popular.
while it looks slightly more mature, this is kinda inefficent. I really prefare the SUPER COMPRESSED IM english where they replace what with: "wut" , over this one.
