The BBC is probably unlike any other media organisation, and, at the risk of sounding like a company man, it is possible to do things that simply wouldn't be possible anywhere else.
Take Audio Drama, for example. Setting up an Audio Drama Website, where practitioners and enthusiasts can post their own material, with the chance to have it broadcast, and promoting professional content to a new audience. I can't imagine any other place where that could be done, but it's something I'm trying to get off the ground.
I'm hoping this blog will be a place for discussing people's ideas about the form, as a precursor to a community that can grow via this, yet to exist, site.
