My thought behind my sole vote to re-open was, while yes, the linked answer provides the tools for the OP to find the answer himself, it doesn't actually answer the question. My rationale is, every question that has ever been asked here is effectively asking for a paraphrase of something that is written elsewhere on the Internet. But if all we did was link RFC documents (or blog posts, or other wiki pages, etc) then we wouldn't really be where we are today.
I think linking and referring the OP to read Mike's post was absolutely relevant. But I also think there was an opportunity to give a more personal answer to the OP.
Between the options of closing and marking as duplicate, or referring and still helping them with their answer, which do you think is more likely to bring the OP back for another question in the future? Which do you think would build a more consistent community long term?
Fundamentally, are we more concerned with becoming a(nother) knowledge compendium? Or, answering people's questions? Because if its the latter, we really ought to give people the attention they deserve, and not instantly assume they didn't Google, or search the prior questions, but really wait to see if their question was a full duplicate vs just slightly overlapping.
In any case, I wrongly posted in chat, and Ylearn suggested I make a meta post about it instead. SO here it is. Where does everyone else stand on this?
