The audio version of Blogs are shite is at the development stage at the moment, very probably never to see the light of day. This is not because we feel a similar level of hostility to podcasts but because they can be quite useful. For example, if I miss something I want to hear on my R
peration device (which I also refer to as a radio) I can perhaps find it somewhere as a podcast.
The problem in the future of these things is that they are actually less interactive than the existing technology. For example, a radio - especially a pirate station - will build a community of listeners (ok, ok "users") and employ texts, calls, and shout outs to maintain a dialogue. A little, in fact, like the comments section on a blog.
The podcast suffers by comparison. In a world of emerging two-way media it is no more than a monologue. If you don't believe me, try calling one up and asking for your favourite song.
