The only good reason I can think of Tinder being used is because it's a well-known app and involves real life social things. I can't think of a well-known game that has in person/real world social interaction like this.

It's a swiping game. Comparison is valid.

I agree, my first thought in seeing this headline, even the applicable market of people is much, much bigger for Pokemon GO. In addition to the entire market of Tinder, there's also kids and married people.

And, as on tinder, it's all about 'catching em all'! ;)
