Set myself up on last.fm, changed to amaroK for playing music (so things go to last.fm) and added foo to the sidebar of my blog. I guess the trick now would be to get something to auto-add my current tune to the bottom of each entry. Maybe :)
I’m a GNOME boy, but amaroK seems to be leaps and bounds ahead of either rhythmbox or the version of banshee that ships with Ubuntu Breezy.
Back to last.fm, I think the goal is to help suggest music that you may like by looking at what you listen to and what other people who listen to some of the stuff you listen to listen to. Seems interesting at least.
Newfangled technology to remove the “so what have you been listening to?” question from the list of things to talk about with friends :)
