You may disparage TikTok as a Vine clone, but it redefined the state of the art for recsys algorithms. Google and Meta had to play catch-up with how quickly and how good TikTok is at discovering videos users find interesting out of the ocean of available content.

Yeah its incredibly disrespectful to call TikTok just a vine clone.

Most of Meta's engagement comes from video content. Continuous engagement is how it is able to generate its revenue.

Thats all I need to say!
