People suck at communicating, but people want to communicate. People love to complain more than they love to fix things. A lot of the time a complaint is half frustration, half trying-to-be-helpful-suggestion. Sometimes it's just people complaining about other people complaining (like the "fix it yourself" crowd or the "didn't you reflect before posting that the issue of X is already a known concern?" crowd) but this just goes back to people wanting to communicate.
I suppose all I really wanted to say was that maybe people in general should open their mouths / comment boxes less. (Yeah my comment sucks, doesn't listen to its own advice...)
It's a hell of a lot easier to be negative or express a frustration than it is to put the energy into a positive, constructive conversation. It's not an easy problem to solve because the different parties to the conversation have different experiences and are often unaware of the situation for the other people involved.
For example, what might have been an innocent question for one person is actually an annoying nag to somebody else, because they've been answering that sort of question for a long time and have built up an expectation for everyone else to do more research first. The person asking the innocent question doesn't know that they're the hundredth person to ask, so to them the response seems harsh and unkind. Someone observing the exchange from the outside is going to have their own judgments on the quality of the community.
The solution to difficult communication isn't to communicate less, it's generally to communicate more and that doesn't necessarily mean more conversations, because communication can take place in many different ways.
What would help even more is to approach communication with some level of empathy and compassion, and accountability for how you react to those reaching out to you (or those you're reaching out to, of course). If it always seems difficult and sucky then you need to understand why you continue to see it that way, why you get frustrated, and what you can do for your part in that communication to make it more pleasant for yourself. And then make that position clear so there's no misunderstanding of intent.
A large part of communication in those terms, and at the scale we're looking at here, is setting clear boundaries on how you wish to be communicated with and how you'll do your best to respond. It's not useful to act out and complain and moan because nobody can guess what it is you want from them.
