Notifications will obviously be a core part of the "my" experience. When a user clicks on a screen that has no new notifications (which will be true for most users the first time), that's a great opportunity to educate them about what notifications are, how they'll work, and whether/how the user can control subscriptions (topic, email/sms/none, etc.).
Signup is a breeze (so far) but some little touches like validating e-mail address and checking password against confirmation password in realtime would be great initial signals to the user that this is a thoughtfully-constructed experience (as well as increasing the success of onboarding).
