These types of question are typically asked by new users who may be asking a question on Fluther for the first time. Their primary goal may not be to find the answer — although they may be curious — but rather to see how the site works.
I think we should be welcoming to these new users, answer their questions, and then politely direct their attention to the question guidelines, which ought to have more specific guidance on this matter.
Also, keep in mind that not everyone is as adept at constructing Google queries as you might be. For some users, asking the question in plain English and getting a human response is a preferable experience. If you find these questions annoying, I’d say it’s better to ignore them than to offer a chiding response that might turn off new members of the collective.
