Here is a rant. With Memes. Because people like pictures, and people like memes.
I see tons of posts on groups and forums with people commenting on or calling into question another member's spending habits. It's one of the rudest things someone can do to someone else in this hobby- plus it's just socially inappropriate and awkward.
(I know there are a few cultures out there where it's okay to discuss things like this or even career salary, but in a great many more it is NOT okay. Consider where you posting before opening your mouth.)
