Could we drop this entire line of discussion and return to photography? To get us back on track, I'll quote the original post:
The issue is much wider than photography and it predates social media. I remember when our company first introduced email (long before microcomputers). Within days there were email firestorms and insulting language the like of which we'd never seen/heard before. Some of it was due to poor language and/or misinterpretation of what was written. Much was caused by people simply being more casual/flippant. In a face-to-face meeting there are body/facial/intonation clues to accompany words. Emoticons are a poor substitute (though they're better than nothing). As someone who, in the past, has administered such communications systems, I can't count how many times I've had to send out cautionary messages, talk to people in person, and even hold "training sessions" on email/digital media etiquette.
In the early days, we talked about the growing need for "digital education", to address issues such as etiquette, truth, and digital malevolence (viruses, scams, trolls, cyber bullying) in this new medium. Most of those discussions were drowned by the
tidal wave of the Internet. I still believe that the basics (language and communication, critical thinking) are vitally important skills, and should be 'top of mind' in school curriculum.
All this is to say that there is no easy solution, especially with international participation and differing/evolving social/cultural norms. One can only ask for and model civility (thank-you, Peter), hope that civil behaviour and language is reciprocated, and monitor/intervene when things get out of hand (hats off to the monitors – it's a thankless job).
