Years ago, when I was still single, I used a bunch of different dating sites. They had very different sorts of memberships. OKCupid worked best for me, and there were certainly a fair number of women who used it, though I’m not certain of the gender ratio.
Men and women definitely had very different experiences of it. My partner, who I met through OKCupid, kept getting men hitting on her who had lied when answering questions about their personalities, in order to have profiles that were more likely to match women. These were questions about beliefs, personality traits, and so on – the sort of thing that lying about would just lead to awful relationships, if it worked at all.
