Profile Pictures

[Kevin Kaczmarek]

In the process of reading "Twitter Power 2.0" and one of the interesting things I read about is your profile picture should be a picture of you, not of your pet, or a landscape scene. This got my attention because it made sense, Make a personal connection via your profile picture. I know on biggerpockets alone I tend to not colleague request people without profile pictures and looking through my colleagues I noticed most had a picture of themselves.

Is there some truth to the psychological aspect of making a connection by a profile picture? Are there success stories on here of building a network faster with a profile picture as opposed to something else?
