I've just landed back in the UK after a three-week round the world holiday to Australia and back via Redmond for the Indigo Software Design Review (SDR) last week.  The SDR gave me a chance to play with a slightly updated Indigo build than the publicly available Indigo Community Technical Preview.  I was going to list the highlights of my week but then I saw that Omri Gazitts, from the Indigo Team, posted a list of his favourite Indigo features that maps pretty closely to what I was going to mention.  My key take-away was that the team have done a great job designing Indigo so that it is feature-rich and easy to use with good extensibility points throughout the system.

While I've been away Mike Taulty (Layers of Indigo, IInputChannel and IRequestChannel, Channel encoding and filtering messages) and William Tay (Message Tracing, Logging and Activity Management and the details of the default Indigo bindings) have both been doing some excellent job of kicking the Indigo tyres and exploring the CTP builds.

I'll write more when I get a fresh VPC image installed with the CTP bits.
