As it stands, I have been on 2 podcast, doing another tonight, have 2 pre-interviews this week, a panel podcast interview on the 20th, and another podcast in March.
It connects people who want to start podcast, people who want to be guests, people looking for guests, and people looking for co-hosts, and of course people selling their services to the folks needing help.
So far, I haven't paid a penny to be on these podcasts and I've made some great connections and even a few followers. If that is something you're looking for - I recommend the experience!
