What's wrong with all those dating sites?
drewcrawford: I think the fundamental problem is that the reason people are on most of these dating sites is because they can't find a date elsewhere.  Building a good dating site means solving that problem:  making dating online more intuitive than flirting in real life.  This is hard, because you've got however many billion/million years of evolution working against you.On the other hand, there are some groups for whom physical flirting is already cumbersome. Busy professionals/entrepreneurs (arguably above-average dating material) don't necessarily have time to chat up people at coffee shops.  People of a particular faith or with a particular medical condition may be genuinely afraid of simply meeting random people.  There has been some success with this sort of 'longtail/niche' dating site.
