How is it that Fluther 'knows' in which section my question will fit best?

Today I asked two question with this one it’ll be three and both times, after writing the details and I was sent to the next step the step where you decide which section you are going to put your question in, Fluther suggested the right section to put it in (first in Social, second in General).
I have noticed this many times before too.
How does Fluther do that?
Is it simply looking at what I use for the first word of my question Can, How, Why, If, etc.
Anyone who knows how it is done?
Or is it coincidence?

Edit: With this question Fluther got it wrong by the way…
