I've noticed something (this might just be me) but the personality of women seems to change from website to website.

From my own experience -

Facebook: Girls are very protective over people they don't know and tend to lash out without warning. The majority of people I talk to on Facebook always have their bitch shields up. I Understand why though.. mostly only people they know are adding them and it's more a place for friends than hooking up.

Doesn't mean it can't be used that way

Myyearbook: I've noticed girls on here are a LOT easier to get along with and talk to. I've scored once off telling a girl plain and simple that I wanted to fuck her. (She was trashy/gothic/emo all wrapped up in one) but had a damn nice body.

Anyone else have different experiences with girls being different varying by site? Myyearbook for me just seems like a place you can say anything and get a response and if you add someone you don't know on Facebook, they seem to automatically be on "CREEPER" alert as I like to call it.

Yes - each site attracts a different style of girl. It's interesting when you see the same girl's profile on different sites - you even get discrepencies in age - and I'm not talking about 1 year either

My take on the sites I've used

Plentyoffish - attracts the down to earth, can be fun types who want fun but not really prepared to pay for a 'proper' dating site. A lot of 'bigger' girls on there. Have met a few from there.

OkCupid - I hate this site but I'll try to be objective - it seems to attract the girls that love to chat, and they like all those quizzes. I've yet to get to meet any girl from there

Facebook - never used it for game - it seems overly protective to me and now too serious. I've tried the AreYouInterested thing and that seems as good as useless. I just got 1 girl interested and all she wanted to do was just add me as a friend - what's the point?

Myspace - again I haven't used it to game - seems much trashier than FB and attracts young people (I'm in my 40s) probably very good if you're in your mid 20s or less

Friendster - good as useless - in my area it seems to have zillions of Thai girls who live in Thailand but pretend they're living in Switzerland - a fucking joke. I think they just use it to chat with friends and family

These generalizations are absolutely horrible.

Those are just my *opinions*. I know that MANY people have a lot of success with OkCupid. I think it stands that different sites attract different types of girl

Can't say I agree with the down to earth thing as I have meet some type A personalities there as well as B types. Tho I agree there seems to be a large population of bigger/thicker girls at POF. But I also seen a lot of skinny/slim girls as well.
I get the same feel tho I have yet to really get a conversation going on that site. But then again I focus more on POF as I have more success there.
Social networking sites in my opinion are pretty much useless with cold approaches. If you know the girl in real life or at least met her in real life then I think it can work more in your favor. Tho I agree that FB is better than MySpace. But that is what you get when it comes to tech as someone makes a product and then someone comes along and tries to make a better product.
Are you sure they are not prostitutes?

Jurupa - they could be prostitutes! but a long way to go for a fuck and pay for it

That is true. lol
