I wonder what that says about dating in general, or just about the type of people you meet on dating websites.
One conclusion could be that the truly desirable* people never need to resort to dating websites.
* [In the sense of "life partner", not "lust at first sight"...]
Of course, that could be said about any mechanism or place where people meet.
Tens of millions people use dating websites. I have no reason to believe that they are not reasonably representative of the general population. With only a few exceptions, the women I've met face-to-face have been very nice. It's difficult to describe nice, but here's what some of them did for a living ... an MD (child psychiatrist); a research chemist; a chemical engineering professor; a PhD engineer at a technology firm; the head (?) of the "philanthropy" department at a large IT firm; a physical therapist; a veterinary nurse; and so on. I even met a marine.
The only girlfriend I met on line is the department chair of nursing at a college. She is a widow (married for 20 years) with 2 children. We dated 8-9 years ago but are still friends. Ironically, for the last 6 years she has been with a man she met on line. She wants to get married but he doesn't feel he is financially ready.
Of the men I personally know who have used dating websites (admittedly a small handful), they are all good people with high levels of integrity and care. With one exception, they are athletic and physically fit. To mention three ... one is a (retired) photographer at a major newspaper; one is an engineer; one is a retired military officer. Any woman would be lucky to have them. In fact, two are now married to women they met online.
Now, perhaps your comment was directed at me. If so, that's fine. It doesn't bother me. But I am offended at any insinuation that the above women and men are not desirable.
I mentioned match.com simply because it is quantifiable. My experiences are equally applicable to women met in other ways (e.g., church, athletic activities, through friends).
I've been on dates with many wonderful women. All the women I've dated more than twice have been great. However, this doesn't change the fact that there was considerable interest in my financial resources. And it doesn't change the fact that they expected me to "do everything" (e.g., call them). There's been only a small number of exceptions.
I remember a date with one woman met through a friend. I liked her. I believe she liked me, or at least that was my impression during and immediately after the date. She said she would call but never did. That made me conclude that my original impression was incorrect and she wasn't interested. So I didn't call her to avoid making her feel uncomfortable. I never promised to call. Later, though, I found out that she was interested in me. She was disappointed that I didn't call. You can criticize me for not being more aggressive. But she said she would call. I made no such promise. The expectation was still on me.
