This conversation is with Marco Arment, who many know as the guy behind Instapaper, The Magazine as well as the lead developer for Tumblr. I wanted to catch up with Marco for some time, but now was the perfect time since he'd just announced his new podcast app, Overcast, at XOXO in Portland.We talk about his early days, app store economics, his love for podcasts, the decision to create a podcast app and what we can expect for Overcast.You can find about what Marco is up to at www.marco.org and find more about Overcast, which is expected to be released late this year/early 2014 at www.overcast.fmYou can find more NextMarket podcasts on iTunes at: https://itunes.apple.com/us/podcast/nextmarket/id579455690You can also find more of my podcast project conversations here: http://nextmarket.co/pages/the-podcast-project
