Some of the points mentioned in this article are good. Additionally, I believe designer's role is not just limited to "design" but to become the most important cog in the product development lifecycle. I personally believe designers should have strong business sense as well as technical understanding. They must understand the limitations and reality of business as well as technology. Like technology you should never outsource your design completely. Its okay give some design assets to 99Designs etc. but not whole design job. Note to OP: You tried to make this page really visually appealing, but it fails on interaction design. For example, those popups for short summary about Dieter Rams 10 principals are annoying and provide terrible UX. You have to wait for few seconds after clicking each box. Why not simple tooltips? Tooltips are not fancy but they are really useful.
