First, there is the blog mindset that seems to desensitize normal discourse. My test is whether I would literally say that post to a group of contributors over a beer. If it seems too edgy or offensive (that is, someone visibly becomes uncomfortable, walks out or tosses their drink in my face), then I try to rephrase it. I try to remind myself of that when I write a post.
Second, we often talk about audio gadgets that we care about, because of ego, expense, and/or time invested in the hobby. Sometimes I forget that folks care about their gear as much as I do. Perspective via self-reflection is always heathy before clicking that “post your response” button.
Third, sometimes written communication simply fails. That’s hard to get around. But it happens.
