I like your point, I agree that you should be careful when using this effect.

However, in proper places blur feels very natural; after all, human eye works this way.

I think blur has lots of potential. I especially like these use cases:

- triggering blur effect after a dialog pops-up

- leading the user through a series of mundane forms, displaying the goal in the blurred background

I'd be interested to hear other ideas too.
