I've actually been a user of the bitcoin buzz app that had "LetsTalkBitcoin" podcasts in the mobile app with stream functionality.  Then something happened to it the podcasts in the app, as they wouldn't display anymore- but i was using it for months to keep up to date on things. I was very satisfied. It seems like they are pulling in LetsTalkBitcoin Blog announcements into the mobile app instead of only the Podcasts.  I sent them an email, and they responded with the fix to the blog announcements.

I haven't jumped on board with this coin yet, but I've been very pleased with the progress Adam and the LetsTalkBitcoin team has made thus far.
