I'm trying like heck to find it, but it's rather difficult. There was a girl on DA who basically drew out what you are suggesting, and eventually went back and did a re-draw of them. I know DA's facebook posted it once and there was a comment by some user saying that the DA persona should have bigger boobs where DA replied "Give us a break we're only thirteen." Or something like that. It's not really a new idea, I've seen it done quite a lot, even people making dresses that represent different websites.
The ones I have seen have little detail to them.... I wants to do the websites I have not seen personified like Gaia for example. And I've only seen the kid forms, no teens. I'm doing a teen with a few adults.
The one I'm speaking of, and I still can't seem to find it, she drew them as teens and they were in pretty good detail. I think most draw them as kids through, or even chibi, is because most websites aren't that old. Gaia is only ten.
