@JackRoad:
I have no doubt that's the case; it's well-known that men are expected to do the pursuing. However I've only message women I have stuff in common with, and ask a few questions about that. Since when I was doing that I was still overweight (though far less than I am now; I could have been described as "chubby"), I'm not surprised that I got a lower response rate than the friend who also wrote intelligent, targeted messages but was tall, thin, and handsome. However he still got only one response in ten.
I should also emphasize that not talking about meeting immediately; I have never suggested meeting immediately. I'm talking about meeting at all. Generally, I suggest meeting after half a dozen or so messages, when we've established that we share interests in common. In short, out of almost threescore and ten messages I sent, I received three responses, two of which lead to conversations, and neither of them with women who were willing to meet. (Including the girls who were willing to share their real name with someone they met on Craigslist, that's 0 for 5.)
I will say that I love that OKCupid has the "would you ever consider meeting someone from OKCupid in real life?" question (and yes, I specifically remember it saying "would you ever consider") and that I can set the "no" and "maybe someday" options as unacceptable. Sadly though, I'm too fat and jobless to try dating for the time being, and I didn't discover that question until I was in Korea.
