I love listening to podcasts with Overcast especially when commuting or traveling somewhere.
I keep a Trello board of podcasts I am listening and want to listen to.
A podcast is just people talking. Nothing magical.
Can use QuickTime to record.
Great opportunity to meet up with others - makes for a more fun show.
Since it's a rather new format, there's lots of room for new concepts and new ideas.
You don't need expensive recording studio. It's just recording conversations.
Basic audio editing is easy to learn. You can use free tools like GarageBand and Audacity.
Podcasts are not necessarily live. You can edit out the parts that go off topic.
Cast - Record, edit, publish, and host your podcast.
