Honestly, the only one I still catch from time to time is Sean on Trek culture because all the other ones got absurdly hostile the last few years when it came to Discovery & Picard and it ended up with people quoting some truly insane alt right sources like midnights edge.
I find it better to just enjoy the shows and discuss on reddit(now lemmy) than watch these influencers.
Yeah it does seem the apps are currently limited in that regard, hopefully development pace will continue and we'll be up to a point where we can do that in the next few weeks.
Once the apps are in a good state we can see how viable this will be long term.
