It appears to me that roughly half of all profile images are either the auto-generated monochrome avatars, or similar non-person graphics, or at best, photos of something clearly not an adult human face.
Does this matter? Is there any reason or incentive to encourage users to place an actual, identifiable picture of their own face in their profiles? I ask because there is also a mix of reasonable-seeming human names and made-up word combinations or even just meaningless-appearing collections of letters and numbers. (Not considering the user12345 auto-generated names)
As something that passes for a community, should we nudge people towards at least having a photo, if not their legal name? Why do we allow anonymity when many large sites are moving to stop it?
