Here are my questions about Mixlr (cross posted from the posterous blog):
Mixlr sounds like a great service. I have a few other questions though:
What is the quality of music stored by Mixlr? CD quality? MP3 quality? This is something audiophiles will be interested in.
Do you plan to convert to a paid service in the future to support yourself financially? If so what will happen to current members?
Will there be copyright problems if a DJ is playing songs, for instance, and then saves his performance on Mixlr? If the performance afterward gives public access to download copyright material you might run into some trouble with record companies.
