@zippy *zing recived* but you should note that i also asked a whole bunch of questions that never got on the show too
your comment releates a little to my feedback though, it would be great if there was some feedback to the user that your question has been seen.
That way you could also present feedback as to why a question is not accepted (its about dates for example) and perhaps reduce double posting of questions by putting a stream bookmark at the time where the question is answered
you could even have a commenting system on questions, lets say someone asks an obscure question about some class deep in the framework, the moderator could mark the question as "unclear" and that would show up on the question in the player, then either the poster or someone else could post a comment on the question, clarifying it. you could even do a wiki-style editing on [unanswered]questions, allthough that might be overkill.
That kind of stuff is probably outside whats feasable with twitter hashtags though, but you could still listen to the twitter feed and take questions from there as well as from the player app it self
Having the questions "in" the app would present other oppertunities for other awsomeness as well, having stream bookmarks for questions would make browsing the 16 hour offline feed much easier. you'd also have the unanswered questions recorded so it'd be easier to go back and do followup interviews later
actually a "question-posting-app" would be great for c9 in general tina and others often post threads taking questions, but i think they are often lost in the general c9 forum chatter, having that in a separate place would be great
