I often see questions with 2-3 answers all having good information but none that consolidates that info. Also sometimes the right answer is in a comment. I always tell those guys to post it as an answer. And to the others I comment there answer and tell then to add the rest.
But very often these peoples do not react. So am I bad posting an answer that's already there on the page, just not in an organised fashion? I know it's quite in the spirit of stackoverflow but still feel bad.
