On the Craigslist homepage (on desktop) there is a gray navbar on the left side of the screen. That area has a calendar and some group of links below it. The second group of links below the calendar includes "best-of-craigslist" link.

I like that the Craigslist site design is utilitarian and hasn't changed much over the years. The downside is that stuff like this can hide in plain sight.
