I don’t actually use TikTok or even the “sliding” function on youtube shorts, but I feel like my attention span has gotten much worse after they started getting popular. Even watching a 2 minute video feels dreadfully long, let alone a 10 or 20 minute video, so I end up watching a mostly short animation memes instead.
If you’re looking for short skits, I’d recommend Joel Haver. This is my favourite video he’s made recently https://youtu.be/yWoDSsCX1S8 followed up by https://youtu.be/3c_BodbA8F4 but he’s done great stuff for years including some very cool collaborations and animations. Mostly in the 2-5 minute range though sometimes he does longer.
