>...If you put a bunch of energy into such a product and it looked like it would take off... bam... Tinder now has videos and you're dead.
Or he could be sufficiently irritating that he is approached for acquisition.
There are segments of the consumer base out there he could go after and use cases we probably are not considering.
Tinder is global and in my country, it has a (bad) reputation as hookup app i.e sex-for-pay. This alienates that group of people looking for something more substantial than a sexual encounter. That's one thing not going for it.
There are other drawbacks. People post their profile pictures, sure, but still misrepresent themselves in other ways.They write glowing tributes about oneself which other people might not agree with .... I for one would appreciate a one minute video of prospective matches to learn more before committing fully .
So, an app with a different angle of attack would generate interest.
Dating is nowhere near a conquered market.
