Is your application doing all these? The list of Facebook integration points

By our count, there are 18 integration points (and 4 semi-integration points) for applications trying to achieve (or improve) their viral growth on Facebook.

The question is: is your application using all of these? If not, you might consider how to use them.

Over the coming weeks, we'll show you more about each of these in individual blogs, so you can do your best at implementing them. Of course, as you implement them you need to include a good analytic package to track how they are performing and how to improve them in detail.
