Explaining REST
Charlie is on a roll. The difficulty with promoting REST is that we can't yet say "Products X, Y, and Z support it", or "Companies A, B, and C are standardizing on it, and so should you". The case has to be made for technical superiority (in many situations) of REST over the entrenched OGC architecture, and that means some jargon and details that seem esoteric to a lot of GIS practitioners. Charlie's latest are good posts that don't require continual reference to the HTTP/1.1 or WxS specs.
