I recently came across a question from the nascent era of Database Administrators; it was posted in August of 2011. At that time, the details about what constituted a good question, and what did not, were still being ironed out.
The question asks for a list of people who have made life-changing contributions to database research. As of the writing of this meta question, it has a score of +11, and has 8 positively scored answers.
If this question were to be asked today, it would likely be closed fairly quickly as off-topic. See the dont-ask section of help for the many reasons this question would likely be closed.
This is the question in, er, question: Pioneers in Database Research
Should we place a Historical Lock on this question? That would prevent it from being edited, closed or deleted, and would prevent new answers and comments from being added to the question. Historical Locks are a mechanism by which moderators can mark posts as historical artifacts. Questions which are historically locked feature the following post notice:
Locked. This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions.
