Suppose that someone on Math.SE posts a questions that is, shall we say, difficult. After spending a lot of time on the problem, seeking help from both Math.SE and MathOverflow, I find out that no one knows the solution to it- in fact, there is a well-known conjecture such that the proof of the original question would follow from it, but this conjecture is just that- a conjecture, with no proof.
So I go back to the OP where the question came from. Despite getting a lot of views, and a handful of small comments, there is not a single response in the form of an answer. Should I write an answer, not exactly answering the original question, but rather explaining that there is no known solution yet, but that there is a conjecture that could address the question directly?
Normally I'd just be inclined to comment, but such a comment would be pretty long; I'd have quite a bit of commentary to put down.
What do you think?
