SDF
SDF (full name: The SDF Public Access UNIX System) is a service that is marketed as a UNIX-based social network. In reality it is a UNIX shell account that has a number of features. Founded in 1987 as The Super Dimension Fortress Macross, an Anime-centric BBS, it has evolved. Very popular among Cyberpunk communities (like lainchan), it has a good series of people logging in daily.
To "validate" your account, you need to send by mail $1 to their HQ in Seattle, WA. This is to prevent spam and help with server costs. For another USD, you can get DF stickers.
To log in, you ssh into your account and then have access to the SDF's TTY.
Basic account features
Mail, UNIX features, two MUDs, chat, dating service, gratis USENET access, free web hosting, etc.
Subscriptions
The SDF server also hosts internet services for subscription rates. These include Dial-Up, DSL, and an ISDN connection.

English wikipedia article for SDF
Cyberpunk is a theme of fiction and a direct decedent on Cypherpunk. Think steampunk, but Computers. A typical cyberpunk society is a dystopia founded on the idea of "High tech, low life". Another common theme in Cyberpunk is people taking technology and using it in a way that it was never intended.
Cyberpunks like older technology, mostly from the pre-1990's era of computing.
