Wondering if anyone here does a podcast, has dabbled in it, or has insight on needed equipment?

I've been thinking about getting some equipment and doing it for a while. Mainly for family, friends, and to have things for the kids to listen to later in life.

Definitely interested in what it takes to do geographically separated recordings (e.g., people calling on phone), since recording conversations with my parents and parents-in-law would certainly be beneficial for the kids later on.
