[Air-L] Podcasting trends research? Experiments in podcast discovery?

If you are interested in trends related to podcasting, I want to invite you to my new niche Local Podcasting Facebook Group: https://www.facebook.com/groups/localpodcasting If you know of podcast or media discovery researchers who might engage the group on how to make the podcasting ecology more effective for those producing locally focused audio content to make geographic interest a more of an organic discovery process, please invite them along. In short, Facebook has figured out how to share "Groups near you" ... how about "Podcasts near you"? Thanks, Steven Clift
