> It is possible that you may even be compromising your career by being good at the technical issues of a job to the extent that some bosses who cannot stay on top of what you are doing may feel they would be more comfortable with a safe, matey colleague than a bit of a strange wizzkid who gets to be known as the oracle of all things. This is always a possibility... however in my experience things tend to fall more on the side of bosses being all too happy to offload responsibility onto that whizzkid and then tuck them away in a box away from any possibility of career advancement. After all, if you can't be replaced, you can't be promoted.
