Just saw another community of diaries. They're the artists' of a record label called Discipline Global Mobile, founded by Robert Fripp. He also leads the band(s) of musicians called King Crimson. Awesome music, to say the least.
The diaries helps the artists keep in touch with each other, since they are scattered across the world. There are some interesting things in Fripp's diary about Napster, the music industry's greed, The The, &c.
