“holy shit I don't own my audience and that was my wake-up call where I was like newsletter I need to diversify I need to make sure LinkedIn I'm thinking about a podcast like I've got to figure out ways that I can connect with people that's not just one platform”

Diversify before the platform fails you

Don't wait for the hack, ban, or algorithm change to learn you don't own your audience. Treat any single social platform as rented land — route followers into something you do own (email list) plus 1-2 secondary channels (LinkedIn, podcast). Distribution risk concentrated on one channel is an unforced error.
