I saw a delete vote on a rather highly voted question Is it OK to split long functions and methods into smaller ones even though they won't be called by anything else?. And yes, I do have the top answer there.
This delete vote confuses me.
Part of the reason the question recently regained my attention is that I got an announcer badge from it (and I don't announce things). It turns out that it is linked from an external resource - ars technica - Ask Stack: Is it OK to split into small functions, even if they’re called once?. I believe it would be a bad thing for such questions to get deleted as they are used as examples of Programmers.SE. (The list of ars technica posts that have an author of 'stack-exchange' can be seen at http://arstechnica.com/author/stack-exchange/ )
Building on this, questions that are used by major news sources bring eyeballs to the site which is a key part of the SE business strategy. Like the questions or not, deleting these questions would be counter productive to the people that keep the lights on at the site.
Secondly, it has been fairly long and established policy that questions that are dupes to other questions shouldn't be deleted. The associated MSO discussion - Do not delete duplicates!
If I am missing something in the best practices for 10k tools, I would appreciate being informed what it is that I'm missing so I too can cast a delete vote on the question with a clear conscious and understanding of how .
If, on the other hand, someone else is missing some part of understanding of what to delete and not to delete, until the question is deleted (and given its high vote question and answers takes quite a few more votes), I would have difficulty knowing who to articulate my comments to (to the best of my knowledge, delete votes are private until they are acted upon), and thus am broadcasting them here.
Tangential question: If Stack Exchange wishes to keep these featured questions from news and blog around (and make note of them?) - should there be a 'major news source/blog' lock to prevent closed questions that have been featured in a way that SE wants to maintain from being accidentally deleted (either by an errant migration and close or misinformed mod or an over zealous 10ker?)
