I asked a question about how to request a historical lock for old but seemingly popular questions that don't meet current site standards for preliminary research (or some other criterion) here: How can users nominate old, popular questions for exemption from closure as being of 'historical value'?
Since I stated explicitly there that my preference would be to preserve the "bare/bear with me" question in a locked state, it's only fair that I expose myself to the wrath of close/delete proponents by reiterating that preference here. Neither the "bare/bear with me" question nor the two answers it drew are especially substantial, but more than a million people have viewed the page since it was posted in August 2010. And though the coverage isn't deep, it is clear and accurate.
I suspect that much of the debate over this question comes down to whether (on the one hand) you think that the "bare/bear with me" question lowers the prestige of English Language & Usage and encourages similar low-brow questions from people who see it, or whether (on the other hand) you think that the primary goal of EL&U is to provide useful answers to questions of English language and usage that people are interested in, regardless of their level of sophistication. As this description of the two viewpoints indicates, it is easy for proponents of either view to talk past the other because one view does not obviously and directly entail the negation of the other.
I'm not embarrassed by the existence of the "bare/bear with me" Q&A on our site, and I think that its presence is unrelated to the flood of low-end questions that arrive here day after day. Those things happen, I believe, because the vast majority of visitors to this site are neither experts nor advanced enthusiasts when it comes to the English language. They are people who want their English-related question answered, and who either ask it here or search Google and find a related answer posted here. This is the central fact that phenry in his famous Meta post This is not a site for "serious English language enthusiasts," and it never will be insists upon: most people who use EL&U are not looking for complicated, recondite explanations of advanced linguistic phenomena; rather, they want to know the name of a color that is somewhere between crimson and scarlet, or a word that means you kind of think someone's a jerk but your mind isn't entirely made up, or the difference between start and begin, or whether you should use "bare with me" or "bear with me."
Five and a half years after the "bare/bear with me" question was posted, no one has attempted to provide a deep answer to it, which suggests to me that no one here who is capable of such an answer is inclined to provide it. That may be because knowledgeable people consider it a fundamentally uninteresting question—but their lack of interest in the question obviously doesn't extend to the Internet community at large. In any case, the 125 people who have upvoted the "bare/bear with me" question and the 224 people who have upvoted the accepted answer to it aren't zero-rep fly-by users: they are Stack Exchange participants who, one way or another, accumulated enough reputation points to cast upvotes on EL&U posts. (I am not among them, by the way.)
Still, if no one has cared to improve on the concise answers posted five years ago, I see little reason to reopen the question (which was closed earlier this month) just to make additional answers theoretically possible. That's why I would prefer to see the page given locked status. That way, it can continue to provide quick practical advice to the many people who continue to find it in Google Searches, without having the cloud of "CLOSED [for lack of adequate research]" hanging over it, and without the threat of its being deleted outright and inviting new rounds of questions about the difference between bare and bear from inquisitive visitors who find their way to EL&U.
So, to summarize, I favor the locked preservation option for the "bare/bear with me" question because (1) I think the page is useful to people who seek it here or on Google; (2) I think the locked status draws a useful line between questions that satisfied older EL&U standards but don't satisfy current standards, and questions that do meet current standards; (3) I don't think the existence of historically locked questions harms the site; and (4) I think older questions that have earned many upvotes over the years deserve a degree of respect and tolerance for having done so.
By the way, no one as yet has detailed the steps involved in giving a question a historical lock. I continue to hope that someone will provide such an answer. [[UPDATE, 3/18/16: Sumelic's answer to my "How can users nominate..." question appears to be a definitive response; I followed the method it described (namely, flagging the moderators with a request for a lock) in seeking a lock for the bare/bear question (as others may have done, too), and a moderator responded to the request(s) by locking the question—without reopening it, I might add. The result is that the question remains closed but is no longer in danger of being deleted. Thanks, mods!]]
