Let's assume that people generally date about 6 months before deciding to get married and let's assume that the average engagement is another 6 months. Given that, there is something wrong if you are signed up for one of these websites and get married in the same year. 12.4 is small.
More likely that being a person unlikely to get married causes eharmony use, but it's true that spending time fixing one's self is probably more productive than spending time on a dating site.
"It turns out you are 12.4 times more likely to get married this year if you don't subscribe to Match.com."
Wow, this was a sobering wake up call about dating sites.
"That is, a man can expect a reply to 1 in every 100 messages he sends..."
I shall pass it along to a friend who recently started using one, I can easily imagine what it would feel like to get a 99% rejection rate.
