While I don't have anything against the hobbyist culture, I feel that if E&R has to become a center of knowledge we will have to start ask and answer hard questions. High level theoretical topics like microelectronics, semiconductors, VLSI, embedded systems, computer organizations, robot locomotion, control systems,materials etc must be included in our discussions if we want to do something as high quality as stackoverflow.
Should we start making a list which will be used to seed the E&R site?
I am in a hurry right now but will submit mine in a short time. Meanwhile, it would be nice if the rest of the community started on a list as well.
