I fully agree. I also hate when people on forums say to use google. If everyone did that, you would just be finding a bunch of forum posts of people saying to use google. I hate when I'm googling and find a post of someone having the exact problem and then they are told to use google and the post is locked. Or when the person found a solution and never posted it. "it works now!" What did you do? We'll never know.
I agree, in the main, but there is a responsibility for people to at least put in a little effort to research so occasionally the 'JFGI' response is justified.
We'd get snowed under with requests for help for things people just couldn't be bothered to make the effort to research otherwise (thinking of one forum in particular where it seemed every third request was a plea for information on how to calculate LED series resistors).
I think we're all guilty of it occasionally though, it's really difficult to come up with appropriate search terms if you're unsure of the terms used in a subject, setting out with your first TE purchase is a big deal but there's a responsibility again to do at least some research for yourself which has obviously not been done in many cases.
Again, I agree, when help is offered it's only good manners to post the conclusion and some detail of the resolution.
I really appreciate all the people who make an effort to share their work on the 'net, doesn't matter if it's a teardown on youtube or a fully documented design and build of a highly complex piece of advanced electronics, it's all useful and contributes to the sum of knowledge so thank you to everyone who does that.
