This happens in lots of different fields. I feel like people need to start developing pseudonyms when they achieve success, so that they still get feedback. Either that, or they have to carefully cultivate a group of no people to hang around and tell them which ideas are stupid.
Stephen King tried this (as Richard Bachman), but he was found out after just 4 books. His last novel as Bachman sold 10x as many copies after the connection was made known.
