The reason pessimism is upsetting is not necessarily because it's negative, but because it's a bad comment. It doesn't spark conversation. It doesn't make people enjoy the thread. It doesn't make people laugh. It's defeatist for no purpose, and on Lookout Landing, we like to encourage commenting that adds value, which pessimism does not.
Question of the thread: Favorite microbrew you've had on tap while on vacation. Or wine or soda if you're not into that whole beer thing.
