I've been an affiliate for most dating sites for a long time. We had a really long run for a while with eHarmony and did a crapton of PPC for several years. In the end I found a broken industry with players who were far less interested in providing good service then generally doing everything they could to play the numbers. Their entire business is built around maximizing conversion and retention rates, nothing more. While I understand ROI (I live and die it for my business) most players also have not made any effort to adapt or change by delivering better value; they simply live by squeezing out another 0.1% Then again, I've been out of the space since April last year and there are many new entrants, so I could be out of date :P
