Thanks for sharing and liking the site. I am the one who created it with a couple of friends.
Tommorris, we are using Onboarding because, as you mentioned the industry uses it. Also, onboarding and signing up are a little different in the sense that some apps don't have a sign in in their onboarding flow. So we want to use a more generic name.. But thanks for the suggestions!
Thank you so much! We want to leave the site neutral. The one thing we want to introduce is some comments from people who worked on it or some data around usability.
I created UX Archive to archive all the user flows form interesting apps. This specific page is dedicated to helping people understand the new patterns Apple introduced with iOS7. Please let me know if you have any feedback.
