I mostly find the odd places when searching on and for discussions of old stomping grounds. That usually leads me down a long path of links. Sometimes I discover by joining oddly named and sparsely visited IRC rooms. Occasionally great sites are posted to 4chan.

A recent discovery was made when looking for recent references to Temple Of The Screaming Electron. This search led me to two weird corners (potentially NSFW).

1. http://www.popeye-x.com/title123.htm As far as I can tell originally set up by a group of programmers (and I think phreakers, digging through the archives ), based in Texas with a common connection to a niche Austin based radio station. Highly original, deeply buried links, multiple hidden forums.

2. http://nobodytm.com Not even sure how to explain this one! Has a chat room that the owner sometimes frequents with cryptic messages that appear to mean something to other participants.
