For me, it depends on the question. Some questions may seem like repeats, but small differences in the details actually make the discussion different, and poll questions are okay because new people have joined, and things turn out differently.
On the other hand, if it’s just a factual question, I would appreciate for people to do a quick google search or anything and try to figure it out for themselves.
Honestly fluther’s seach tool sucks. It just does, so I’m somewhat forgiving of repeats because newbies don’t often realize that the easiest way to search fluther is through google.
