It’s interesting to see someone else tracking what they’re listening to. I try to include the .mp3 or other audio files in my post with proper markup to create a faux-cast of sorts that others can subscribe to. Somewhat like reading.am, I find that discovery of podcasts by seeing what others are actually listening to is far more valuable than what they simply say they’re listening to.
I’m hoping that podcast apps like Overcast by @marco might support technology like webmention and micropub in the future to make some of this stuff a bit easier as well as more valuable.
