While this link has gone through many other sites already, I wanted to inlcude it here to make sure every dev in the world reads it!  It is an excellent list of the types of influencers that have made me decide to quit being an independent in the past and try to be an employee again.  If you are workign for someone else, print this out and leave it on their desk.  Its important that non-dev’s read this and understand it.
