I will say it depends your own feelings. But as said in the podcast by Skeet I guess, it's good to answer question with the same effort as the OP does ask his question.
So big question, with lot of details deserves good answer. Poor question does not.
I think accept rate may be an indicator of poor answer in a way (new user asking only question) but not only.
Less than 10 reputation does not mean bad user as well, but new user. So you may find unexpecting question coming from them: could be bad (very bad) or very good.
So I will say look at the question. Does it sound clear, interesting and not just
gimme teh codez like? if yes go on. It's up to you.
