You've introduced a new idea here by comparing FogBugz to Facebook.<p>Those earlier comments are comparing the <i>strategy</i> that Fog Creek took versus the one that Facebook has taken. The strategies are similar, and so the comparison makes sense.<p>It should be noted that Wasabi <i>is</i> a general purpose programming language. It is Turing complete (up to relatively trivial finite-memory issues, just like any other general purpose programming language). Like C, for example. It should also be noted that Wasabi is a .NET language. It has full access to the .NET Framework and all of its classes.<p>One could use Wasabi to write a C compiler.<p>[NB: I am a Fog Creek developer, working on the FogBugz team.]
