About a year and a half ago I was an active OkCupid user for several weeks. The concept of personal compatibility based on questions you answer and answers that you mark as acceptable/unacceptable sounded absolutely unique, and I had high hopes for the service. Invested lots of time to answer more than 1000 questions, large chunk with custom answers too.

However, at some point I realised that most people don't put much effort in filling out their profiles, answering a dozen questions at most. Still, the compatibility algorithm would suggest such people, which made the whole reliance on questions based compatibility rather moot. And that way, OkCupid is just another generic dating service with swiping based mechanics.

Given that there are more modern alternatives in this space, and OkCupid is hardly "trendy" anymore, how reasonable is it to invest one's time in swiping people there? Is there any data suggesting that OkCupid is in any way better for the user than its competition?
