Say I have asked a question on the site before, but I either received no or no satisfactory answers. Then, after too much waiting, I decide to write my own solution.
Is it okay to add that solution as answer to my own question?
Would it make a difference whether the solution I created is FLOSS (open-source) or proprietary?
Sure you can, you are even encouraged to – see Can I answer my own question? in our help system. About open-source vs. proprietary: it should of course be open-source … if the question requires that (honestly, FOSS is always a good idea). But then, as it is your own question, you are the one specifying the requirements. The answer should match those.
As you speak of your own product here, just make sure you don't forget the obligatory full disclosure that this is your own product 😉
