I've noticed that a lot of questions with several 'answers' aren't upvoted, or are disproportionately upvoted (6 answers, 1 upvote). Is this normal or expected?

To clarify, the question being asked isn't upvoted.

Common reasons:

• Don't want to give reputation to non sysadmin/IT professional questions.
• Question itself wasn't interesting, but answers were.
• Don't want to increase search engine results for some questions.

Suggestions:

• Comment on the original question to help the asker improve the quality of the question itself.
• Make the question a community wiki so it can be modified by others to improve it.
