Just shipped Incarnate, a new lab from the fresh new looking Mix Online site. I think the appropriate tagline for Incarnate is "Who do you want to be today" as people are quickly realizing that it can be more entertaining to be a celebrity avatar than yourself.
Now you know what all those posts about JSON-P, Windows Azure, REST Starter Kit and more were about!
And, as you may notice, I've implemented Incarnate on this blog, inside .NET Blog Engine. Unfortunately, I couldn't use their plug-in model and I actually had to modify the source, but it wasn't too bad. If you are running .NET Blog Engine and want to know how to install Incarnate into it, let me know.
