The most awesome Hanselman app built in about 4 hours to showcase a sample of Xamarin.Forms. Be sure to read Scott's blog: http://www.hanselman.com/blog/XamarinFormsWriteOnceRunEverywhereANDBeNative.aspx
In this sample Hanselman app we show awesome information about the awesome man who is Scott Hanselman including reading in his blog & parsing with XDocument. Additionally, I use Linq2Twitter PCL to grab all of Scott's tweets, all using a nice MVVM Style and nearly 100% code reuse.
Pull in Hanselman's podcasts and stream them on each platform.
