I chose infosec.pub because I think it has a good chance at longevity and will be managed well.

DFIR Diva also has a wealth of info on her site:

I really like this podcast but it is not updated on a regular schedule that I can tell:

I am also interested to know how this will be supported financially as I know servers are not free. Will there be a Patreon like on Mastodon?

Salutations! I work in DFIR, have for the past couple of years. Before that I worked in IT - Systems Administration for a long time.
