I updated with the paper comparing how TikTok is beating FB

All I'm getting from these is TikTok has a better recommendation engine? Am I missing something?

Has anyone scrapped all three to show for a newly created account there is significant difference in topics or something like that?

The academic research is scarce.

This is the next one I found (from a high schooler though)

It doesn’t look like a well researched area in terms of academia. I am not an expert in this so don’t know why

Thanks for linking and kudos to that high schooler considering how much in the news it has been you would expect it to be a well reasearched area
