i think an "audio only" community would actually benefit from anonymity, a lot of people who are EXTREMELY ONLINE are afraid to let their online friends hear their voice. being able to listen to a thread as a conversation has potential.
and that's to say nothing of music share threads & remixing
My last anonymous board experiment was federating anonymous boards ....which was a bad idea, but at least I did it ,so I can say it is a bad idea.
