In researching my intended post on SLebrity, I was unable to find a comprehensive list of Second Life subcultures. I took a quick shot at an outline that is depicted here, but realize it is very incomplete.
If you'd like to contribute to building a more comprehensive set, please post your list in the comments section. I will aggregate contributions and then create a revised image.
