Hey say_hello,
Thank you for the kind words and your review, I really appreciate it!
The Like box and faces are actually part of Facebook's official Like Box widget which we add to the top of bottom of the feed and so we don't have much control over it apart from a few settings. Facebook uses an iframe to load the Like box and faces into your page after the page has loaded and so sometimes there is a delay in them being displayed, as they have to be loaded from Facebook. When I refreshed your page I saw the Like box and faces appear after a couple of seconds, and so it seems like everything is working correctly but there is just a small delay in displaying it. How long of a delay are you experiencing?
