I'm not sure women have changed "because" of the seduction community, I think society has changed enormously due to social media etc and so have the ways in which women view their interactions with men but I am sure that these changes have had a huge impact on how the seduction community functions in practical terms although a lot of the theory behind the practice is still very much the same.
Due to social medial peoples attention span is much shorter and they are looking for excitement or at least stimulation they find enjoyable all the time. If they're not getting it they move on. Women and men are much more educated in the broader aspects of life that they used to be sheltered from in a lot of cases so there is a greater awareness of the opportunities out there so don't get drawn in unless they are interested.
I think also as we as individuals go through life our perspectives change as do that of women we interact with. There is always some shy girls and more extrovert girls etc but as we get older, girls and guys, we become more direct at going after what we want, or at least more efficient. Therefore we are quicker to dismiss what we are not interested in.
20 years ago I would have persisted chasing a girl in hope for ages, now I just move on. Consequently I go through a lot more people of an evening but I still think that there is the same "mix" of people there has always been, it's just that now I see it from a completely different perspective.
I guess it's a case of "The more things change the more things stay the same". We as individuals change as we travel through life but the overall mix of different people in society remains much the same. We are different people at a different position on the ladder of society.
1) women are more upfront and less coy about their attraction.
in general? I think as we get older we meet a different age range of women, when we were young the young women we targeted were less upfront. There were young women who were upfront but they were therefore not attracted to us and were looking for older men. Now we are older men we see them but they were there previously we just couldn't get their interest.
2) Women are quicker to dismiss you if they are not attracted.
3) Women are more upfront about their "check boxes"
Given the way social media works I'd agree - but not sure this is in response to the seduction community - just the way society has changed
4) Women will ask a guy out rather than wait for the guy to ask.
This used to happen occasionally but I was too naieve and inexperienced to handle it. Now I have the experience it doesn't get this far before I have asked her out anyway.
