However, there is a high percentage of the ones that do post a photo will close me just as soon as I send First Questions. Kind of like they are trying to send a message "so now that you see I am good looking you are interested but you are just a shallow jerk". I also cannot recall that of any matches that did post a photo to a Photo Nudge that may have gone on to communicate that it ever made it to a meeting with the exception of a couple that were FCWers.
