Clarify intended audience

It seems to me that, both naturally and from the HN post, that most people are going to be looking for practical decisionmaking help in understanding the available open source components and architectural paradigms in building real world distributed systems.

Right now the intro reads In this text I've tried to provide a more accessible introduction to distributed systems. To me, that means two things: introducing the key concepts that you will need in order to have a good time reading more serious texts, and providing a narrative that covers things in enough detail that you get a gist of what's going on without getting stuck on details. It's 2013, you've got the Internet, and you can selectively read more about the topics you find most interesting.

While that sounds fun it could be a little more explicit about the angle taken within the coverage. Didn't suggest a push to the intro since it's your book after all and I am interested to know what your thoughts are.
