close on "outside" - just wondering, is there any other reason why a user would click outside of a modal either than to close it?
IMHO, you're comparing apples to oranges with this example. What I'm talking about is when you load up a page and immediately you're greeted with "HEY! LIKE THIS PAGE ON FACEBOOK!" I get annoyed by modals that auto load. Especially the ones that are set to a 5 second timer.
Real world example if the world was the internet:
User is walking around a mall.
User sees a store he's interested in.
User opens the front door of the store.
Immediately, store owner appears right in front of the user's face.
Store owner puts a sign in front of user's face.
Store owner says "Before you walk into my store, READ THIS!"
If I were the user, I would immediately leave. I don't know anything about your store. I was only curious and already you are forcing me to look at things that I didn't come here to look at?
