You're right, of course. I considered mentioning the possibility that this was meant more as a test PR style or tongue-in-cheek "Haha this is obviously super important"-style post, since these are definitely viable explanations, but I felt the rant was already long enough and I couldn't find an easy way to work it in.
One of the most dangerous things about sharing stuff with others, especially isolated items from unknown authors with a worldwide audience, is that you never really know how much of their own context the recipient will read in, or how much of the assumed / pre-requisite context they'll fail to infer (or infer differently than intended).
You only get better at this through repeated practice, but you can't ever be perfect at it. Especially in a world of complex social interactions where people don't always mean what they say or say what they mean, and the lack of body language and facial expression in written language silently corrupts the signal.
All readers should always remember, it is easy to criticize. It is much harder to do. Critics especially need to remember this, because it's very easy, automatic in fact, to fall into a pattern of judgment and criticism when we're regularly exposed to so much stuff from so many sources. But it's good to get out there and try, because it's often much harder than it looks, and especially if you've been on the sidelines judging for a long time, it can be jarring how much harder it is to do than to say (or, particularly, deride).
A great way to test this: if there's some radio program you listen to regularly where callers can share a brief anecdote or story, call in. As a regular listener, you've been silently evaluating callers on a daily basis for years. You likely have some opinion about the practices of good callers and bad callers. Call in and you'll be surprised how nerve-wracking it can be, even for someone as "experienced" as yourself, and I think you'll be disappointed in your overall performance (unless you've thoroughly rehearsed ahead of time).
This is just a tiny, irrelevant thing that most people wouldn't give any thought to, a quick ~60 second phone call. You certainly don't give much thought to it every day when you dismiss anecdotes or stories told by amateurs. But try it yourself and you'll get a great deal on some perspective for the difficulty gap between doing v. criticizing.
The peanut gallery can, and will, always find something to nitpick. Don't take it personally. Use that data to hone your interactions and get a better-tuned result next time.
