Hi
Earlier this summer we launched our first Silverstripe implementation for a client. What I found appealing with Silverstripe is the "run all" filosophy - we are able to use whatever markup, CSS and JavaScript libraries we'd like, without SS interfering.
We feel there is still a lot of magic going on under the hood of SS, but we're turning a bit more magic into science on every project. :)
