For about a year and a half, I've been involved with a very interesting online community in Worlds 3D chat.
Worlds.com, or Worlds 3D Virtual Chat, is an online chat from the mid 90's that featured virtual avatar, a predecessor to Second Life. Worlds is littered with remnants of late 90's culture, including a promotional world centered around Britney Spears.
Strangely enough, in 2011 the nostalgic look of Worlds' graphics brought an unexpected, new userbase to the decrepit Worlds virtual worlds to explore its user-created worlds and 'spooky' members, spurring its own 'creepypasta'-esque lore.
