The other day, I was talking with Frank about exceptional software programmers able to influence notably a whole company by their own activity or impossibly better than the rest of the programming crowd. This person is the one you need to hire when you have an exceptional entrepreneurial project or the one you want to identify, protect and feed while waiting for such a project. Weirdly, I just read a random article that gives a more detailed description of the phenomenon and gives it a name: The Free electron.
Worth reading. Worth keeping.
