RosieRad:
Do most people comment on a story they didn't enjoy?
I do, because I have a ridiculous obsession with statistics and want the overall comments numbers to increase: for me they're the measure of the communality of the Library. And if I've got as far as reading something to the end, even if I didn't rate it much, I'll be polite about it (our school motto was "Manners Makyth Man"!).

RosieRad:
I usually just quietly close the window and don't say anything.
That's very discreet of you. I didn't know these windows could be closed quietly. Presumably when you
have enjoyed something, you jab your finger loudly on your mouse/touchpad after commenting?
