Most Helpful Girl
It's to encourage everyone to be as helpful as possible, rather than just give one word opinions that help no one.
As for questions - sometimes, we can't help you without knowing what you're really going through, so the minimum is there to encourage everyone to be as specific as possible so as to receive the best response.
The minimums are short enough to make it easy to NOT see that message ^_^
I hope that clears things up for you!
