I tend to get new designers involved in some of the newest projects we're doing. It's great for a new designer to start on that project, rather than the existing version … because I want to see their new ideas help drive the new product. If they start by working on our already established stuff, they don't get to bring as many of their new ideas and creativity to the project (since the design language is pretty well established already). When I hire someone new I want them to help drive us to new places rather than have us drive them around to places we've already been. That's the wonderful thing about new blood.Jason Fried.
