Who actually does this? What makes you pick a particular number of stars? I see a lot of the threads have "ratings" next to them. I've never even considered rating a thread (let alone how to do so!), but apparently some of you on here do! What makes your decision when allocating stars? Not going to lie, they seem pretty arbitrary to me (i.e. the "5 star" threads aren't always more interesting than the "2 star" threads).
