As the second of my mixes got pulled from Medi@fire, I’m experimenting with alternative platforms. Pod-o-Matic seems to have potential. It even sends things through iTunes [RSS] which is all very exciting. I’ll play with it for a while before investing in a Pro account.
I notice that it renders files into cheap n nasty 96kbps so for the moment, stick with dodgy ol’ Medi@fire until I can do better.
