I think that's hit the nail on the head, Maisie. It does add to the camaraderie, and promote friendly exchanges. Also, sometimes it's nice not to have to admit to the person you've asked for a hint that you've got no idea what they're on about!!
I think in future, if anyone does approach me for a hint, or I approach someone else, I'll use Giraffe's grading system, and actually ask for either:
Check
Nudge
hint
clue
explanation.
And just really hope I don't need too many of the last variety!! (Which, to be honest, I did with a certain fishy puzzle).
