One thing which will never stop entertaining me is the suburbanites who spend their days on my local newspaper site trashtalking the urban hellhole. I think it's hilarious! I don't care if people are city mice, country mice, or suburban mice. People make choices based on their preferences and constraints, financial and otherwise, and good for them! I have some opinions about public policy related to such things, but that's not a knock on individual preferences and choices.
I don't know what motivates them, but I hope they never stop. It's always a source of merriment. It's a weird hobby, I admit, but we all need hobbies.
