As a user, I'd probably still opt out, and I usually say no to sending crash reports (only remember seeing them on Windows stuff). But if I could see the message being sent, I might be more likely to say yes. On the developing side, it's interesting having no idea whether anyone's using what I build. I assume not, unless they tell me, so seeing my apps pop up in Zapstore packs is a fun surprise. @78ce6faa…f026307d could add metrics (# of downloads, # of follow packs an app is in, maybe similar for the dev's profile, if easy to do). That wouldn't acheive collecting usage info, but would show whether it's in use.
