A while back, Fractured Atlas had a link to a post on the Official Google Blog about the meaning of Open. I finally got around to reading it and, boy howdy, it should be required reading for contemporary culture. To a certain extent, it is aimed squarely at the realm of software and technology, but really it is simply about digital culture today.
Also, on the actual subject of digital culture and theater, I was about to sign up for a subscription to mailing list software, and then I realized something: I use Linux! I bet you there's free software that does that! I'm going to see what's up and let you guys know if it works.
