Social Sub-Networks, for characters from different genres

One of the main points of the Magus Device is to have in-character profiles, allowing comrades-in-arms to have conversations, privately or in public, while away from their players' standard gameplay environment (gaming table, LARP meeting place, or logged into the server). To that end, I will be creating subnets for each genre of character, to create a "plausible" social network that your character has joined. Each subnet will have its own style and color scheme, not to mention it's own name.

I am looking for suggestions for names for the various subnets, and the genres they will cover. Possible genres that have occurred to me are: High-Magic Fantasy, Space Opera, Hard Sci-Fi, Near-Future "Gritty", Cyberprep, Steampunk, Gaslight Fantasy, Modern-day Creatures of the Night.

Any ideas for other genres to cover, or names for any of these subnets, would be greatly appreciated.
