The Infinite Scroll Design

Offlate, several websites, notably Quartz and its Indian counterpart Scroll have been using the Infinite Scroll format.
What is your take on it?

Personally, I feel it is good, but only works well if you have loads of content.
I've been told that it is a pain for SEO purposes, but it can be pre-rendered for Search Engines.

Any thoughts on this?
