Haha. I don't care if women want to show off their boobs and such, boobs can be beautiful. I just find it completely disturbing when people do that sort of thing online for the sake of "Internet attention". I agree it's human nature to enjoy a bit of attention (I like attention from my friends, family and SO of course) but I think when you need it from random people it's a bit strange. I also don't appreciate people encouraging the " girls online" stereotypes. Maybe I am too harsh but it goes beyond this as well.
The thing I appreciate about the Internet and forums the most is that any interactions I get (well most) aren't due to how I look. It's nice when people will just talk to you for the sake of talking. When I see people coming on here and posting pictures of themselves as an introduction, or informing everyone of "risky" things, or the classic "hey I'm a dumb girl, it's cute right?" routine it basically makes me want to puke. To me it's like the thing I am thankful for the most (conversations without influence by physical aspects) is the opposite of what they want and I guess I find it... primitive.
At the end of the day I don't spend my nights thinking of these people and getting sassed, nor would I say anything in person to them but eh it's the Internet and I can afford to do it. I like to speak my mind and sometimes it's pretty hilarious what type of response I get. Maybe that's sick, I don't know.
TL;DR if you want to flaunt your boobs go ahead, but don't do it for the sake of taking pictures and posting them online IMO. Other people will have different opinions and that's cool by me though. Sorry this isn't very sassy. ;p
