Here's what happened with that question:
Jan 15 - 4 answers (one of which came the closest to actually answering the question)
Jan 16 - 8 new answers, then question is protected.
Jan 17 - 2 new answers
Jan 18 - 1 new answer
Jan 19 - 0 new answers
Jan 20 - Question closed
Of these answers some have since been deleted. One such answer (the one that prompted it to be protected) was the following (reprinted below in its entirety):
"to see if there is still water in it before opening"
The question was open for 5 days. It hit the top of the Hot Questions list and attracted a swathe of 'I have an unsubstantiated opinion on this' answers. The vast majority of these answers had comments from multiple users and even mod post notices placed against them requesting that they provide some actual reasoning or sources behind what they state. Of all these answers only one poster made the changes to their post.
Now I do agree that the question itself is not where the problem lies here, it is with the multitude of opinion-based answers. I added comments to the main question following the protection (four days prior to closing) requesting:
I'm protecting this question because all the new answers are all saying the same thing but none so far have really given an actual reference for their reason, it's all just opinion. This question is about WHY it is not 'speculate wildly based on no research'.
This question was closed because it was a specific question asking for a definitive answer (exactly what a suitable question for this site should be) but was attracting answers that did not answer that question. Many people speculated, some with better reasoning than others, but only one provided an answer - and that was posted on the first day the question was asked. All of these answers overwelmed the question, gave the impression that UX accepts any old crap as an answer and you don't even need to back up your opinion.
This question also hit Hacker News. In fact it hit it twice which often contributes to an influx of opinionated, unreasoned answers (they don't seem to realise that when they link to something their own readers will go in and contribute, and then in the HN comments they moan about people on the linked site not knowing what they're talking about, but I digress)
A comment on the HN thread sums up some of the problem these answers had:
Thank you, I'm not alone into thinking most UX stuff is BS. Another platform for 'talkers' to look like they build.
I understand the concept of making the interface intuitive and easy to use and I am all for it. But my God, some of the BS I've heard from people to justify crap is insane.
Most of them aren't worth their salaries.
I'm interested in UX as much as any of these goons. Difference is, I can actually code/build it as well.
Quite a long answer from me this time. It was left open for quite a long time closed with the best intentions - to keep the quality of the content up and not full of opinionated, unreasoned answers from people unwilling to improve their posts even when prompted to do so.
Having said all this, I've reopened the question. Lets hope it doesn't hit HN again this time, and that (hopefully) we can get an actual answer this time.
