List of Lists
Okay I'm starting the list of lists here. There is a new link to the home page of one of the lists. Beyond_EM is I think one of my favourite lists, it is supposed to be about discussion of electronic music, but the list membership is very much a community so we end up discussing all sorts, (past discussions include cars, computers, Lord of the Rings, Charlotte Rampling, Charlotte Church etc). The noise to signal ratio is high but the noise is so entertaining we wouldn't do without it. There is also an associated chat channel on Undernet, where a few of us hang out on a Friday night.
You might find if you are lucky that you are chatting in a message thread with one of the many musicians there, but then there are so many musicians on the list it would be hard not to speak with them.
