PushingUpRoses doesn't do gaming content much anymore, practically every video she uploads is about Murder She Wrote or sometimes other old daytime TV, and I'm just not into it. If it's working for her more power to her but I guess I'm her "old audience."
Vsauce went from a kinda smarmy gaming channel to that kind of smug "look at a bunch of random smart things that ultimately don't matter" show, then stopped uploading regular episodes for awhile and instead created some long-form ready for television crap on Youtube Red or whatever that subscription-only service that failed was, and then kinda puttered out.
The Modern Rogue has done a lot to make it difficult to be a subscriber of theirs, and both the quality and quantity of uploads has gone downhill. They're apparently still at it, but I dunno man.
And a whole bunch of 'em just don't upload anymore.
