Designing better mechanisms for dating sites doesn&#x27;t have enough leverage on which dating sites become useful and valuable. Like, matching markets are well understood and very effective, but AFAIK there isn&#x27;t anything in the online dating scene that works that way. It&#x27;d be straightforward to replace a Tinder-style swipe-fest with &quot;put up profile &amp; rank the profiles you see, then go on a date with the highest ranked profile that doesn&#x27;t want someone they ranked higher&quot;. There&#x27;s no point to doing that without a marketing budget.
