Sara has a great entry where she looks at how we are doing so far when it comes to making approachable source code. 

Sara Ford's WebLog : Power Toys as Shared Source, Collaborative Development Software – Where we’re at and where we want to be.

So, after countless meetings with the Shared Source Initiative team, Bill Hilf’s team, my fearless mentor on OSS down the hall, WiX’s Rob (including staying late one Tuesday night to watch the team code – it’s crazy what I’ll do to succeed), and the CodePlex team, I have an idea how to kick start the collaborative-development for our power toys.
