Compliments on the site.
While I don't agree with *all* of the material you've got, your section on 'Nice Guys' had a lot of very good stuff. At the risk of speculating on the inner workings of the female mind, I'd like to offer my theory on the whole nice-guy issue:
The vast majority of women don't want nice guys.
That's right. Sorry, guys who were hoping to get lucky by rescuing puppies and listening to Yanni, you're in trouble.
Women don't want nice guys. In my experience, with friends, partners, and other interactions, they like *KIND* guys. The difference is a subtle one, but it's important.
'Niceness' is a set of completely superficial behaviors that boils down to 'being inoffensive.' Someone can be a 'nice

' just as easily as a caustic

. Niceness also comes along for the ride with kindness in many cases, but is motivated by genuine care for others regardless of how it 'pays off.'
My experience has been that most of the deeply embittered 'nice guys' are just as self-centered as the jerks they gripe about; they just don't have the balls to weather rejection from healthy women while playing the numbers game, hitting on women until one responds favorably.
If your goal is to 'get' a girl, and you're trying to accomplish it by being a nice guy, you are being very inefficient. If your goal is to form long-lasting relationships with people you care about, and possibly have a romantic relationship with them, well, kindness is a quality to cultivate.
It's about motivation, really.
