Apart from a few friends that I've made, I've also discovered some very nice bands. One sore point is that my new employer does not allow me to listen to music at work, let alone install the plugin. At least I have my own laptop now, so I can continue scrobbling.
Here is a list of artists I've discovered at Last.fm:
Runrig #3 in my all-time list
Cara Dillon #9 in my all-time list
Leland Thomas Faegre
Here's to many more happy days with Last.fm!
