https://cake.co has been quite good for AMA-style interviews lately (which they call "Panels"). Victoria Taylor (/u/chooter) who used to do a lot of the big AMAs on Reddit is working there now, and they're doing them in a more moderated way where people have to submit questions instead of just being a frantic free-for-all.
First page is confusing, looks like a twitter clone or something?
The second like is easier to understand, although I am not interested in reading a plain interview with self promotional Qs and As. They feel very unauthentic compared to AMAs (although IAMA definitely had a point where it because too self promotional to bear as well).
