I generally have a lot of animosity toward iOS app badges. I don't like apps screaming for my attention. It diverts me from important things, like Strategery. However I was recently bemoaning my frequent problem in the Drafts app where I'll dictate notes and forget to later process them. MPU listener Conrad pointed out there is a setting that gives the app a big red needy badge with the number of unprocessed notes in my Drafts App. This is an excellent use of a badge in my opinion and was exactly what I needed to make sure I didn't leave unprocessed notes in Drafts.
