Members are disgruntled that the Podshow interface makes it very difficult for listeners to find the podcast's home page. In fact, some are speculating that Podshow is deliberately hiding that information to make listeners stay on the Podshow site longer. Others are taking offence to the fact that although the 'main' RSS feed problem has been fixed, there are still multiple feeds for each show and there are still errors in those feeds.
I am not listed on Podshow (a great decision in retrospect) and I'll think I'll wait until the furor dies down before I put my own show in harm's way. I have to say, though, that it seems quite clear to me that Podshow is either actually up to something, or they launched eons before they should have.
The basic problem is that Adam Curry is involved. If anyone else (except possibly Dave Winer) were heading up Podshow, then the "Oh, it's beta, give us a break" line might fly. Sadly, Curry is one of the freakin' podfathers - there's absolutely no way this stuff could have slipped by him as unimportant. Either Curry doesn't actually have his hands in the day to day development and running of the system, or...well...he's up to no good. Only time will tell which it is.
