demogroup
n.
[{demoscene}] A group of {demo} (sense 4) composers. Job titles within
a group include coders (the ones who write programs), graphicians (the
ones who painstakingly pixelate the fine art), musicians (the music
composers), {sysop}s, traders/swappers (the ones who do the trading
and other PR), and organizers (in larger groups). It is not uncommon
for one person to do multiple jobs, but it has been observed that good
coders are rarely good composers and vice versa. [How odd. Musical
talent seems common among Internet/Unix hackers --ESR]
