It seems like every web post has an accompanying headshot of the author. One of the things I like most about the internet is the casual anonymity, like we don’t know who the other people are at all, all we have are their words and their ideas. We evaluate them solely based on what they say and no other criteria. It seems kind of democratizing.
I have been using computer/text communication in some form or another from 1987 (modems) to now (PC, cell phone, etc.). For most of that time, you had some kind of handle, like Twitter without the verification or the real name, and no photo of any kind. I really think it works fine.
