Podcasting as a communication tool?
At the MA Conference went to this useful session about podcasting - seems acheivable and I'm wondering if using sound files that answer audience research questions might be another form of giving information via a q&a? In response to your query about how audience research is used in a museum it could be interesting to interview people about their use of research or projects they've worked on and then post this as an easy way to capture and distribute information rather than having to write it out? Might be a useful student resource - once I get the right equipment you and I could give it a go?
Anyway, the museum detective website has useful tips on podcasting and many links. Joanna Cobley spoke about this and I have blogged about it at my conference notes. Worth checking out.
