"I don't get my info from Google". Then use your search engine of choice, "google" is basically genericized by now. The info is all there for you to read and not rely on your memory which is clearly wrong. And that's understandable. It's been 10yrs.

And you're not entirely right on the YouTube not stealing users from tiktok. YouTube shorts have more active users than tiktok does by a good margin. And tiktoks growth is slowing as a result. Again, these are all facts.

And finally, you're a fucking idiot. Why the fuck did Instagrams user count explode when they implemented short form video if that wasn't an attractive feature? Why is my Instagram feed 85%+ videos over pictures? I don't even follow celebrities on there, a handful of bands (be less than 10), the rest is friends but mainly content creators creating comedy. Be it memes, original creations, stand up clips, etc. Your memory is shit and fallible, the pages I literally just read are not as they are saved for posterity. I suggest you take my original suggestion and do some research on the topic instead of relying on your feelings before you make yourself look like a bigger idiot. Cos yeah, Instagram didn't take 100% of vines users, but it still took a fucking huge amount of them. The data is all out there, written way better than I can write it. Go read it and stop trying to act like you know all, cos after you read a bit, maybe you might change your tune...
