Ahh, Conan. How things have changed since you become the Governator. ;)
Frankly, I don't think about meeting women on sites like this. If it happens, it happens, but my focus is on stimulating discussion with like-minded people and the hope of finding people near me who aren't into repetitive meetings at the local community hall debating how evil religion is, how the country is bending over for the religious minority, etc. There's so much more to life than posturing against irrational concepts like religion, supernaturalism, etc.
I don't believe in hooking up. The only way that ever seemed to work for me is to randomly meet people I think are nice. Getting into a community with similar-minded people of course helps that, but I am here for enlightment, nothing else ;)
Why must your main goal in life to be to meet someone to have sex with? You actively search for it, solely. Isn't it more interesting to actually get to know a person for real?
