I'm looking to promote this site and want to hear from our domain experts what our best questions in each discipline are. I'm interested in both questions with great answers and also great questions in need of answers. Overall, quality is what I'm looking for to entice more people to visit and contribute.
Why am I asking here? I can pick out some great meteorology questions but distinguishing good from great outside of my expertise is a bit harder to do. I realize "great" is a bit subjective, so really I'm just asking for questions that you think show off this site within your domain of expertise.
