I read about this cool new website Odiogo, which will enable the readers to listen to blog content as well by adding audio files for each blog entry. I am not sure how many people out there will be interested in listening to blog content as audio files, but neverthless i think the idea is pretty good and sounds interesting, they are offering this service free so I went ahead and signed up for my blog. So you should now see the icon "Listen Now" on top of all the blog post and by clicking that you could listen to the blog post in audio.
I am personally not happy with the quality of conversion to audio format, but i think they would improve on this aspect.
