I never used TikTok but from what I heard and saw it is essentially a Vine with better UI and UX e.g. you scroll vertically for new videos and it has very good recommendation system. P.S. I never used Vine too but then again I read and heard about it. TikTok won because like other guy said; videos are the most immersive media and I claim that people having short attention span made them hungry for short form of entertainment like short videos. From time to time I watch compilation of TikTok videos on YouTube and I think "compilation" as a media form is another interesting thing that somebody should experiment with. Speaking of social networking; my understanding of social networking/media landscape is that Facebook sort of generalized social networking and social networking features and now apps like Instagram, Snapchat and TikTok are specializing in photos, ephemeral sharing and short videos respectively plus WhatsApp specialized in messaging but Zuck did a great job of making Facebook Messenger a standalone app and then specializing it according to demands of messaging crowd. And yea Zuck acquired Instagram and WhatsApp along the way so competing apps don't hurt Facebook and its family of apps.
