Permies is a place for
perennial discussions. We have threads that are still running from 10 years ago, long after the OP (Original
Poster) has fixed the problem they started the
thread about. This is not a question and
answer forum, where a question is asked, it is answered, and it goes away. In the future someone with a similar problem may search for a solution and find the thread. Some of the answers that are not relevant to the OP may be relevant for them. Because of that, replies tend to be all kinds of related solutions, not necessarily specific for the OP's parameters, but they may be relevant for someone in the future, who has different parameters, and can still learn from the thread.
What do you do about answers that are not relevant? Ignore them, or thank them nicely, and see if you can politely word why, so maybe the next person knows a few more of your parameters.
An example, I don't recall which thread I started that I was dealing problems with my brush cutter. Someone said "I use a scythe." If it had mattered, I may have said "Thank you for the idea! I'm disabled and on bad days can't even lift my scythe, and I have 4 acres to cut, so I really need my brush cutter to work right." so that maybe he could have given me a more focused answer. It didn't matter, so I ignored it. But in the future, someone may say "Whoa, I never thought of using a scythe where the brush cutter can't get to due to the slope!" And THAT is EXACTLY what Permies is about, giving ideas to
people that help them find solutions that fit their parameters, sometimes many years from now.
So relax if you are getting answers you can't use,
be nice and realize that someone else may be able to use them, and that is what a perennial discussion forum is set up to do.
