Complexity in Virtualization Opinions

needed a full page to explain that there is no way you can keep up documenting or building a product on top of a proprietary product such as VMWare because they will change things you depend on behind your back.

What I still don't get however is why he keeps interviewing people from exactly these kind of companies.. companies that build on top of proprietary software that have little added value themselves. Yet he gives them good advise however..

But I`m wondering how much of a disaster tourist he really is :)
