How many people skin
 

A lot.

Especially high school kids. If it's skinnable, they collect the skins. if they have any photoshop skills, they create new ones. Mostly Winamp and other MP#/Audio players, but IM programs come in a close second.

I think I hear your wheels turning.

I used to skin my WinAmp. I don't bother anymore though.

winamp is the only thing I skin

never.

There are tons of people who collect skins, but don't make them. Getting to be someone's default skin would be quite a challenge.

winamp most of the time
mediaplayer..rarely..cuz i rarely use it lol
and some other things.:p

I dont skin at all... cutomization can be cool, but I prefer customizable content to skins

same here
