Facebook Developers

As of August 2006, Facebook has offered a free Developers API called Facebook Developers. This essentially gives anyone access to Facebook’s internals and lets programmers create widgets, mashups, tools and projects based around Facebook.
This is an important feature for Facebook since it makes it the first major social network to give access to its API. Although it is limited to 100,000 requests a day, it’s more than enough for a decent web app to come through. What’s more, a selection of applications have already been created. Facebank is a promising tool which lets you ‘keep track of depts and shared expenses with friends.’ Another interesting application is lickuacious which lets you ‘rank your friends by wall popularity.’ The Wall, of course, is Facebook’s comments feature.
