Should we post questions we intend to answer ourselves on the Sandbox, and if so, should we post the answer we plan to write in as well?
I'm asking this for a particular reason. A while ago I posted this question, which I proceeded to answer:
How much energy would be released in a collision of planets of matter & antimatter?
It got some major bad press. I'll admit it was poorly phrased and built. My grip on LaTeX liquified, I was in a hurry. We're all human; we all make mistakes. But I got hit over the head with VTC's and downvotes. What was worse was that there weren't many comments until after I was put on hold, which should have been avoided. I think I got 4 VTC's in 1 minute. I rephrased the question to make it fit into the scope of worldbuilding as defined, and tried to close a duplicate answer. But I found myself wondering how something like this could be avoided in the future. It wasn't an experience I wanted to repeat. I wanted to include a fun-ish tidbit of useful information that counted as worldbuilding and might help other worldbuilders.
I'm getting used to using the Sandbox a little. I'm even getting used to welcoming new users, directing them to the tour and help. I can suffer downvotes and realize that my answer/question is bad. But I'm still unsure as to the whole answer your own question scenario. This post is about three main questions:
Should I post questions I fully intend to answer myself on the Sandbox?
If yes, should I include the answer I am aiming to post to my own question?
And how can I resolve similar issues in the future?
I get that this is often a result of bad questions and answers, but I'm not looking for an explanation based on that truth.
