I'm an old BBS'r as well. I agree that online sensitivity seems to have gone up. Perhaps it is in part because the digital aspect of identity is greater for people born in it? I'm not sure, but my guess isn't that we older folk have thicker skin, but are just less invested in that arena. I'm skeptical of actual differences in generations. IMO the snowflake hypothesis is a perception based on differing values, not that younger folk are any more or less tough. I'm not saying that's what you are saying. Just typing as I think... The thermometer idea is interesting. I do believe how we signal appreciation or structure threads, strongly influences the type of interactions we have. I'm open to experimenting with it. However, I do not see my agreement with a comment as a positive thing. Ideally, I would like to be able to indicate that I find the comment to be stimulating and constructive without implying whether I agree or not. I wish shares worked this way, but I think they do not.
