I'm still waiting
Day 2 with TypePad and so far, so good. Radio Userland is an odd amalgam of both a thick and a thin client – some days it feels like the best of both worlds and some days it feels like the worst. I expect that Rogers Cadenhead's Radio UserLand Kick Start will help me eliminate some of the lows once it's available.
I'm still waiting for TypePad to reveal it's inner nature.
