We (a friend and I) built a simple application[1] that gave folks relevant clothing for the weather in their location.

We shelved the infinite scroll at the time out of haste.

It turned out to be a happy accident, as active users refreshing would generate a ton of pageviews.

Not only that, but the act of clicking refresh to "get more" is a nice way to get the user to engage.
