I deployed HN Trends to Heroku's new Cedar Stack and it was simply awesome! It stayed on a single dyno the entire time (I tried scaling it to 2 at one point, but quickly realized that my use of an in-memory object that needed to persist between requests was not "shared-nothing") and it handled the rush of traffic with only 1 small hiccup. I got a little nervous when Tim O'Reilly linked to the site from his Twitter account, but Heroku handled it with ease.
