Jemima over at dotjournalism has a great comment about the rise of text-to-speech podcasts:
So yes – an inevitable innovation, but not one that does anything at all for the medium of podcasting. This technology must be ergonomic, rather than built around the convenience of the producer. It will only work for people when it has been humanised.
If you havnt visited dotjournalism then you should. How Jemima manages to find time to produce so much stuff I will never know.
