I’ve been in your position and in the other person’s position many times. It can be frustrating but we need to think about the big picture. It’s possible you hadn’t considered a certain approach, and it’s probable that many other future readers will not have considered a certain approach. So even though you might have said that you want to do something specific, it’s often helpful to some people to provide general information of another way to tackle the same issue.

And of course you know your own situation, so now there are these comments that appear off topic, and they kind of are, for you, and that’s just how it is on forums.

The other situation that comes up a lot is that people are doing it wrong. They are misusing some piece of technology and while their kluge might kind of work right now, it’s setting themselves up for bigger issues in the future. Of course no one appreciates it when you tell them they’re doing it wrong.
