I like the idea of specialized post types. One of my favorites is the Repos (source code repository) post. Having specialized places for different types of content is pretty cool. I realize that it's not a completely new idea (Slashdot has had "categories" since the beginning of time) but I like the way that they have presented it.

Some people here have commented on not liking the "material" design, however I find it head and shoulders above the HN layout. It's fully responsive, lightweight, and fast and looks good on a retina screen. The best thing is that I don't have to have a 3rd party plugin[0] to make it usable. :)
