It's basically all dead air. I think I'm the only person who automated a show.
There may be a connection there.
There is. When shows aren't automated, if people can't be arsed to broadcast on their allocated timeslot, nothing gets broadcast. It's easy enough to write a script to broadcast a show at a given time for a given amount of time -- and when you do, your show broadcasts during the appropriate timeslot even if you're asleep or dead. I strongly recommend it for anyone getting a timeslot, since it avoids the whole problem of determining whether someone is late on their show or merely not bothering.
Cram, I wrote a script that runs shoutcast's little broadcasting app in the background, waits two hours, and then kills it. It's a little more complex now, because it also posts an announcement to twitter and refreshes the playlist, but that's basically the brunt of the script. Then, I set a cronjob that runs said script every Tuesday at noon EST. The script can be made available if anyone is interested.
