I've been recording something each week that I release to complete strangers in other countries, but don't make that much money for. It is a fun hobby my wife and I do together and with friends, though. I'd say it forces us to sit and talk once a week, which is really cool and provides an outlet for whatever we're thinking about, since we don't have a structure/format. Just realized this wasn't "how has podcasting changed your life". Sorry.
