Some people don't like podcasts and would rather read text because it is scannable. Now there is hope. Enablr will turn your podcast into text. They seem to be moving toward offering a text based RSS feed of your podcast. Cool.
In a few years, I'll problemably just drive down the road, see something that inspires a blog post, call a phone #, say what I want, and this blog will be updated with a text post and an audio link. What will they think of next? (problemably an A.I. program that will blog for me.)
