I like them. Sometimes I want to watch videos, but not get super involved in a longer production. Plus, youtube shorts, at least, often have links to the main video they were clipped from, which I'll throw into my "watch later" playlist.
Not everybody likes shorts, and that's fine, but I make them work for me.
Kinda like all the memes in this /c/? I have a hard time believing that every meme here was made by an ADHD person.
