I asked this question at least 3 months ago: "Is there an intuitive understanding of the Halmos-Savage Theorem?" It's received two upvotes, but few views, and no answers or comments.
- You can "bump" your question by editing the question to provide status and progress updates resulting from your own continued efforts to answer the question yourself, or to explain why the existing answers didn't work. I usually do that unless I really hit a dead end with no further clues to follow. Sometimes I eventually bring about enough understanding to realize the answer, and then post a self-answer to my question.
- If you have at least 75 reputation points, you can offer a bounty, promising to give some of your reputation to the user who correctly answers your question. This causes your question to receive additional attention, as it will be added to a "featured" list and be promoted more than normal questions.
- Post a link to the question on the site's chat. Usually active users of the site will hang out there, and they can offer further help.
- Use the share button beneath your question to advertise it to your networks. Then, if you find the answer, you can post a self-answer to help others who come across the same question.
Do not post your question a second time, as it will be closed as a duplicate of your first question.
Expanding a question using explanations that make it accessible to a wider readership may garner attempts to answer the question. For example, providing links and definitions for infrequently used terms like "Radon Nikodym derivative." That is, there are many more people who are competent to answer in a general area than there are for a narrow topic with incidental experience. Moreover, in the case of the introduction of novel concepts to a narrow topic, the experts for a narrow topic are the last ones worth asking about it, such that general knowledge is much more valuable to solicit than particular knowledge for exploring novel concepts.
Changing tags or adding general tags with higher numbers of followers may help.
