Who Dares Wins is pretty much spot on.
The guys that don't have a Facebook are a little weird or are trying to hide something- such as lack of a social life, lack of value, etc. I'm going to be brutally honest here. Most of the guys that say Facebook is bad are either:
1) Ugly (and hiding their lack of social life by not having FB)
2) Socially awkward
3) Old. No one goes on at their age, no one posts anything, the women just use it to spy, etc. Facebook is more of an under-30's thing and I can understand why the older generation sees it as useless.
or,
4) You are doing it wrong. A lot of guys have profiles that make me cringe.
Facebook is a social networking site. In this day in age, it's just another way younger people communicate.
I'm probably going to be the first person on this site to say this...Facebook is AWESOME! If you aren't using it you are missing out on a lot of parties and events. I get invited to events every day through Facebook. Many of these events are private and you have to be invited and on the Facebook guestlist to get in. Most parties I go to aren't advertised through text message...they are advertised through FACEBOOK.
A TRUE Don Juan is a social person. He has male friends with value and he has female friends with value. If you are a true Don Juan then Facebook is an awesome tool for being the first to know about the "happening" events in your social circle and area. If you have a good social circle and you actually get out there then you should have at least a modest amount of the following:
1) Pictures at parties or unique places. Post up pics from that party with your bros, that awesome night at the concert, that time you went backpacking, that time you went sailing, that time you went shooting in the desert, etc. Have some shirtless pics or some pics showing your propensity to have a good time. If you are a social guy then you are most likely a fun guy to be around and you do adventurous stuff. This will show in your pictures.
2) Have pics with girls. Need I say more?
3) DON'T have pics that you took of yourself. This shows that you are a foreveraloner who sits in his room and takes pictures of himself in his room.
Don't use Facebook to hit on girls. Wtf man. If you are even half as good as you say you are you don't need the internet to meet girls. And you don't have to add girls that you just met. Put your profile on private and tell them you don't add girls until the third date. I've NEVER had a problem with this.
And if a girl asks you for your Facebook then she smells something fishy. I NEVER have this happen. The only times girls have asked for my Facebook was when we were already legit friends (NOT when I was hitting on them or prior to a date). When you hit on a girl get her phone number. If she asks for your Facebook then that means she wants to interrogate you; which means you need to do some self-evaluation, because you are giving off a weird vibe to girls.
Anyone in his teens to late 20's that complains about Facebook is doing it wrong. Yeah, that would be cool if everything was still face to face and kids still went outside and actually played with each other, but that's not how it is anymore. It sucks, I agree. I only recently caved and got a smartphone after having a flip phone for three years. I think technology has a lot of inherent problems that come with it, but that's just the way it is. So you can either whine about it or you can take advantage of it.
