Yes it's true the more open and the more you lay out on the table the better chance you have to connect with someone. The whole social thing has always been powerful. The thing is to open up and take interest in others, people in general don't care as much about you as they do talking about themselves.
I do like reading a good intro though. Waite and see you have exposed enough to stimulate curiosity.
