If you have a Twitter account, you can follow KGNU and receive brief messages about what's happening on KGNU -- who's DJing, what bands are appearing live in KGNU's Kabaret Room, special news events, etc. Even if you don't have a Twitter account (you don't need one), you can go to http://www.twitter.com/KGNU to read our "tweets".
We also have a Facebook page. Add KGNU as a friend (you do need a Facebook account to do so, though).
