I know that self-answering is generally encouraged on SE. However, I thought Puzzling.SE might be a bit of an exception; by and large (although not always) askers already know the answer. So can we self-answer, if we want to show the solution to our puzzle? If so, under what conditions should we?
What usually happens is that puzzle authors give hints; first, simple nudges, but I've seen hints which spoil half the puzzle, so to speak. Depending on the type of puzzle, posting a simplified version which introduces techniques to solve the main puzzle may work. Also, a bounty may help getting more attention to your puzzle too.
Sometimes it's difficult to give hints without spoiling the puzzle entirely. I guess in that case you could self-answer it eventually, but only if the solution has any value by itself. What I mean by this is that the value of e.g. a connect-wall lies in solving it, while a clever geometry proof may have some value if it isn't posed as a puzzle.
Finally, we have many unsolved puzzles here, and while it can be frustrating as a puzzle-maker that your challenge isn't solved, one day a new puzzler might successfully pick up your challenge (or a veteran may have a second look and a moment of brilliance). If you're specifically thinking of your latest puzzle, it's only a week old; some users might be on vacation or otherwise not visiting Puzzling Stack Exchange for that long.
