Well, you're not tied into using strictly F#. The C# MVC framework, or really any web framework, will play nice. The majority of an application like the one the article suggests will sit on a server, anyways. Once you're in server-land, things like web frameworks matter less because .NET already takes care of what you need. F# already has well-supported testing frameworks which integrate into Visual Studio, distributed computing frameworks, database interactivity, graphics libraries, and a slew of others. You can find plenty of testimonails of using F# for large-scale and enterprise systems. F# and C# are really just your tooling for .NET, which is sufficient for a massive-scale project. Whether or not .NET is appropriate for the project is a different story altogether - I wouldn't use it for anything that's close to the metal, for example.
