When I first started adding Facebook to websites and blogs it was tedious and barely ever worked like it was supposed to. Even when I was using Facebook’s own tools, they still didn’t work right.
One bug in particular that I kept running into was that the generic “Like” button wouldn’t show the number of likes until it had more than 3 likes. I happened to run across a site that showed the full view even when there was “0” likes. After picking around their code I found the plugin they were using, it was called Simple Facebook Connect and it’s a WordPress Plugin.
Once I installed the plugin it required that I create a Facebook App to attach it to. It was a breeze to setup and the plugin walked me through every step. Since then I’ve used this plugin on every site that we’ve built and haven’t had a problem yet.
