If you read my posts lately, you'll see that this is the only site i link to. There is a very good reason for it. Put simply, this guy just gets it. What he says might be contrary to everything you hear from your "all knowing" friends, but if you have had quite a bit of experience with women, you will realize that almost all of it is the truth. This guy will tell you like it is, and you might become bitter, but sooner or later you'll realize it is the truth.
One word of caution - no matter how great the guy is, you must realize that you are not him, and should not want to be him. You must have your own ideas as to what you are looking for (in females). Be careful not to get it mixed up because you will end up in sh1t.
Oh yeah, there is another side effect of visiting his site regularly, you will start using more sophisticated language, you will swear a lot more, and you will be called an "*******" more often. In my experiences at least.
