18 Facebook Client Libraries

19 PHP Cons Only works with XML Pros Super-easy to use. (like BASIC, but with dollar signs) Written in PHP Officially supported Conducive to spaghetti code Wider variety of hosting options

20 Python Cons Shared hosts don t tend to support Python Uses simplejson by default Slightly larger learning curve for beginners Pros Very well written API Supports JSON/XML by default Easily integrated with Django Good enough for Slide

21 Ruby Cons Difficult to move from PHP to Ruby Bends the rules on how to write RESTful code Pros Scales well Ruby on Rails can be very clean Easy to write poorly performing code Rails encourages automated testing. Not quite conforming to Very Web 2.0 Ruby coding standards

22 .NET Cons IIS, or mod_mono Some aspects require.net 3.5 Very enterprisey and complicated Tied to XML with a noose Pros A variety of existing UserControls Usable from C#, or VB.NET Tight integration with Visual Studio LINQ support Very well documented

23 Other Libraries ColdFusion Perl Java C++

24 More Cons Platform moves too quickly Marketplace API Status API Data Store API Very little shared coding standards Everybody s reinventing the wheel
