I had just discovered that I lost 35 rep points because of the deletion of a question I answered some time ago.
I was puzzled because looking at the cached version in google (I cannot view deleted answers) it doesn't seem to be such an ugly question.
Yes, it is not a great question, but it has no downvotes and although it was closed as off-topic (the user was a newbie), the problem is not utterly trivial (pointers in C are tricky and the error of the OP is not blatantly stupid).
Besides the lost rep (it hurts a bit, but it is not such a terrible loss) this made me realize I had spent some time in trying to build a complete and (hopefully) useful answer. Maybe I haven't got the hang of it yet, but I thought that trying to answer questions from newbies was not "frowned upon" even if they are not super-great.
So do I have to refrain from thoroughly answering a simple (but decent) question for fear of seeing my work deleted? And if the answer is affirmative, doesn't it mean that newbies will find SO a less welcoming place?
