Sogs, definitely. That's a lovely word - just needs a meaning to match.
The great thing with the Mudcat is being able to leap from thread to thread by links, and click to links to other sites that bec ame relevant.A CD-Rom could do that, but with the messy bits left out, except where dealing with it was in some ways a positive experience. And where a song came up, a sound file could be linked in.
This could be fun. Only hassle I can imagine is it might really take off, and the Mudcat gets inundated with tourists and vandals.
