I think one important aspect is that you, personally, need to have a following. It's the same as in other areas like blogging and vlogging. You have to create yourself a persona that people will follow for some reason and then they will consume your content.
My persona might suck. My persona is there is no persona. I'm a dude building and deploying web apps. I use a lot of different tools and try to share everything I've learned along the way.
I don't play anything up for videos or interviews. I'm almost exactly the same in real life other than I'm a little more unfiltered in real life.
I did a meta episode on the show where I interviewed myself at https://runninginproduction.com/podcast/100-running-in-produ.... Since the show is guest oriented I try to let them speak as much as possible (they are the star of the show) but in that episode since I was interviewing myself I got to talk a bit more.
