##The following is just my opinion. I've been using Ask Ubuntu for about 3 years, so by now, I kind of know which question is a duplicate.
Basically, most of the questions that get duplicated, are asked a lot.

So after a while, you can tell.
But usually, if I'm going to answer a question I do a few things.

• I start by looking at the related questions in the right column. The system is quite smart. Most of the times, the duplicate is there.
• If it's something that's quite common, where in my mind I would be sure that someone must have asked such question before, (for example, those apt-get permission denied questions) I search quite a bit to find the duplicate.
• If neither of the above, I do a quick search. If I find a dupe, I flag it. If I don't find any and I know the answer, I answer it.
