Good afternoon Marty,
I think attitude is important. It is better to have some connection with the individual in the image, rather than a shy disconnect. In my opinion, that enables the viewer to become part of the image. Thought you might like this:
This is Magnum providing different images each day. Largely some famous and well known photographers, lots of veterans of photojournalism, and lots of film users. If you scroll down a little, there is this great photo essay from Bruce Gilden called Fashion Magazine; not really so much fashion as a tongue-in-cheek view from an interesting photographer from Brooklyn.
It is sometimes stated that the camera points both ways. In other words, your personality can probably come across in your images, when they are successful, depending upon how you define that. While that is not strictly defining street photography, I think it is important to remember that in your approach to imaging; let the viewer get a look at you, not just your subject.
