Here is Instagram’s founder and CEO, Kevin Systrom, validating this

deliver-value-quickly notion as a key to Instagram’s success:

“In the mobile context, you need to explain what you do in 30 seconds or

less because people move on to the next shiny object. There are so many

apps and people are vying for your attention on the go. It’s the one

context in which you’ve got lots and lots of other stuff going on.

You’re not sitting in front of a computer; you’re at a bus stop or in a

meeting.”
