Is anyone using typescript?

Details
TypeScript:
We have started using TypeScript and the Web Essentials VS2012 extension in our ASP.Net MVC applications. The primary reason was to encourage C# guys in the team to get involved in the client-side JavaScript development and out of their C# only comfort zone.
Does anyone else have any similar experience with moving C#/Silverlight/MVVM guys over to Javascript and found TypeScript a welcome tool to help the transition?
We have found that TypeScript, coupled with good JavaScript frameworks and SDKs including jQuery, kendoui, knockoutjs, RXJS and amplifyjs provide a similar development environment to that of Silverlight/WPF. The same design patterns we are familiar with can be used in large scale JavaScript apps.
We also found that TypeScript helped us produce better quality JavaScript and uncovered various badly written functions. TypeScript also helps you focus on organising your code as if you were working in a XAML/Smart client application.
There may not be any appetite for a meeting on this topic just yet as TypeScript is in it's infancy but it may be interesting for a future meeting agenda.
