What a weird question? This is just a site. It's like asking...do you know I google a lot?
Yeah, everyone knows about this site. My sister, brother, mom, dad, grandma, relatives, friends, co-workers, you name it.
Just kidding, it's not that important for people to know, is it? This is my homepage so if they use this computer, they'll know about it, but for now....until they ask, I'll just keep it a secret I guess.
