Not to be a dickhead, I know what you mean.

Questions that involve some kind of processing power can be a good target for Wolfram, but then, how much marketable besides academia?

The answer to the population of X country/city/town = wikipedia, plus more facts you may be interested while doing your research paper.

Maybe I just need 10 different questions/implementations of such service to get it.

Couldn't you just do this:

askwolfram "What are all of the questions that will ever be asked?" | askwolfram "How do I format this answer for wikipedia?" > wikipedia.html
