Ask HN: Why does StackOverflow close so many useful topics?
Often when searching for information on something technology related I get linked to SO and almost always the information on SO is great. I have also found that a lot of these topics have been closed. For example there is a SO topic on HN front page right now about Language to use for Safety Critical Software. This has been very popular on both HN and SO and yet the topic is already closed on SO.
I find this rather frustrating as it seems that almost any question about "what is best?" or "how would you do this?" is closed, irrespective of how relevant the question is and how good the answers are.
It seems that in their zeal to prevent religious wars the moderators are closing very interesting, relevant and well reasoned topics.
This behaviour does not make a lot of sense to me and is starting to detract, in my opinion, from the usefulness and relevance of Stackoverflow. Just where is one supposed to go to get these types of questions answered from domain experts?
