I hadn’t heard of Twitter Design Director Martin Ringlein before this talk, but regardless of his exact background, he’s a natural speaker, and I loved his frankness when it came to worker capacity prior to burning out. It’s really a talk that can apply to almost any fast paced/startup profession, from producers to designers to web developers. Martin goes off on some tangents near the beginning which pad out the length of the talk, but I’d still recommend it to almost anyone.
