On the contrary. Over "twenty five years", things change, and the question asked 10 years ago, or last month often times hasn't been answered, and still, some self-centred guru will brow-beat newbs for having asked it again, or they quote back a obsolete answer without checking it first.
If those who answered the same questions for 25 years (overkill?) ago hate answering the same thing over and over, they should just ignore the question because the time it takes to shame the newb could have been spent saying ''That was answered here" (and provide a good link).
I read a lot of others questions and responses and must disagree with your assumption. I think a lot of people will do their own research before finding a forum, registering, confirming, posting, waiting, and wondering. It's faster to search the Internet or Google the catalog before falling into the Forum rabbit hole. I do. After a million years (in your time-line of things
), I think I'm very good at searching. I search here - a lot, and when I do post a question, it is because I couldn't find the answer there or here. Maybe I didn't ask it right, and if not, perhaps it is because I don't understand the issue, or most often, it's because I do not understand the response from a guru whose reply assumes I understand
Too, sometimes times I find a responder didn't read all of the question and other volunteers see it's been replied to by another onsite guru and pass it by and we don't get a related answer.
True, but again, a question answered 2 years ago may not apply to today's app, distro, release, update, upgrade (whatever they are called this week). I tried GitHub and ran when a person hit the kill switch on my post because it had been answered. Didn't say when, or where but I did track down a response and it was close, but close only counts in horseshoes and grenades.
Before I'm reeled in by anyone with "so what you're saying is that all volunteers are...". No, I'm not putting down volunteers as most of my posts here testify to so let's not go there.
Less we forget that most people are different than all others (thank a deity or Darwin for that), and everyone has irked moments now and then and the hard part is being on the receiving end of someone's ire - and it begins.
Volunteers should remember that maybe the OP DID search and couldn't find the answer because perhaps they don't understand the issue, saw a answer and didn't know it was the answer, or as myself, dove right into Ubuntu with no recent experience or understanding of it, or the language used by some responders that reply vomiting geekinese.
As one who is a million years old (according to your watch), and having been 'puting since 1981, I still get lost with all the new words for old terms.
In conclusion, before I use up my allotted bytes, I really want to see Ubuntu become the world's leading O/S; that it is the default on every new computer and Windows has a few small 'Contact your administrator' end zones. But that won't happen as long as any Linux distri(bution) flavour, colour, (version?), is still too convoluted for most people. When Linux is as simple as sitting down to Windows, then I see the day when there is the Lite version, and expensive one.
The above is just my humble opinion based on my own experiences and observations and refers to forums in general and is my feeble attempt at speaking for myself alone, not all newbs. And as for volunteers, I very much appreciate the help they have provided here, and the one thing I do agree with you about is ...

... which is probably why our community supplies better and more straight-forward answers,...

p.s. Sorry, but I cannot 'like' your reply because it is too assumptive in that it seems to put too many into the same vat but I guess it only takes one non-searcher to erode the image of many.
