While doing some research on Facebook Apps today I came across these excellent (albeit a little old) videos on TheChickenTest on the anatomy of a Facebook application. I’ve played around with Facebook Apss before, but to be frank have never really taken the time to get to grips with them as a whole, only ever really focussing on spot tasks and specific requirements.
Check out the below, they’re required viewing as far as I’m concerned for potential Facebook App developers.
