In your question you state:
I think general questions on how to conduct market research are fine,
and I would like to understand why you feel this way?
To my way of thinking, a question should be startup appropriate and not at a level for a large established company.
There is already a site, stats.stackexchange.com where someone can ask about the vast majority of statistical and practical aspects of survey design and interpretation. Among the specific topics they cover are:
designing experiments, collecting data & statistical analysis, applied or theoretical
Why would we want a market research question here that overlaps with (or is perhaps more appropriately on) stats.stackexchange?
I undoubtedly did not make clear the first time which aspects of marketing research I was referring to.
Personally I would consider a marketing research question that is in some way unique to a startup to be on topic.
I would not consider a general marketing research question applicable to any organization to be on topic.
In this respect I believe my opinion is counter to Zuly's to the extent that she considers all "general" marketing research questions to be appropriate.
I would agree with blunders comment:
To me covers the real issue, how do you know if a question is for a
startup (new type of business), a new business (the execution of
existing known type of business by a new entity), or general business
(the enhancement of an existing business). My understanding is the
site is just for startups.
Perhaps it would be appropriate to consider an analogy to an accounting question:
I would consider on topic:
I am starting a small business, what low cost software is available to do accounting on my PC?
I am starting a business and buying a new PC, do I need to capitalize it of can I expense it?
and off topic (although) great accounting questions:
Which accounting software is best for handling inter-company eliminations and consolidation? (If you are managing a conglomerate you are not a startup)
How do I insure my accounting conforms to Sarbanes-Oxley? (SOX applies to public companies, once you've gone public you are no longer a startup)
What is the difference between single-entry and double entry bookkeeping? (nothing unique to a startup)
Marketing research in particular: The particular issue with marketing research is that to be of value it needs to be done properly and does involve a bunch of math and statistics. consider a question as simple as:
I am trying to decide whether I should sell Coke or Pepsi in my new store, how do I do market research to determine what my customers prefer?
I'm building a website for my new on-line business to sell widgets, how do I conduct market research to select colors and fonts for the website to optimize sales?
These type of questions on how to conduct research, while clearly startup related, do not permit simple yes/no answers. In fact a complete answer to either of these questions would probably run to several pages and include terms like "double-blind study", "confidence intervals", "sample size" etc.
Viewed from the point of view of which marketing research questions permit simple answers, they pretty much boil down to the type referenced by Zuly in her question. While the referenced question are far from examples of great questions, they definitely could be edited and improved. Personaly I like questions like:
Where can I get population data for US counties? (census bureau for free)
I want to sell coffee beans online, is there any data on which countries buy the most coffee per-capita?
In the US who spends more on books, men or women?
but that's just my opinion.
