that may be against the 'rules', i don't know anything about it but to me it makes sense... i was not going to ask you “what the hell is wrong with her?!”, i'd rather say "hey nice idea, why didn' t they think of that!"
i just think that podcasts, and well including videos, are great mediums to incorporate into blog sites...each has its own advantage that should help the site deliver what it intends to showcase... if all these mediums (text, audio, video) are used on blogs, and if their potential could be harnessed then it's very likely that the quality of the blog will improve... about that question you have on not being able to get rid of the old audio player, it couldn't get erased by deleting the program, the usual way? if so, can you describe what exactly happens?
