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.
SponsorBlock (if available on your platform) is great for skipping that kind of annoying filler. It’s user reported so it can sometimes be a bit aggressive or just missing. But I have mine set specifically to only skipped sponsored segments and it works quite well on bigger channels. Sometimes getting tagged within minutes of publication.
