A few of us are on Myspace. I went looking for us and well, the only Daily Kos related group on Myspace was one that disparages this group. It's titled Krazy Kos and I won't link to it.
I've started a group called Myspace Kossacks, for those of us on MySpace who would like to use MySpace to connect to one another as well. The membership is private and I have to add you (this should stop any wingers from joining the group and generally messing things up.)
Here is the link if anyone is interested.
