While not having read that much Iain M. Banks, I find myself thinking in Culture Ship names an awful lot. Blip.fm seems to encourage it. I try and think up a culture ship name that sums up the song I'm going to blip. No idea why. I enjoy it greatly however.

Well, no – intriguing more like. I really just need to knuckle down and read a lot more Culture
