On the other hand, it's impossible to remember what it was like to not know something. So often, just giving hints isn't enough. When I used to spend too much time answering S.O. questions I tried to, as often as possible, include a working snippet. One, to prove the solution worked, but two, so the questioner could start with working code.

Starting with working code is the number 1 thing for me because then I can start adding to it until it breaks and can always go back to working.
