I think that's a very insightful point, and I agree.

As a side observation, I think you can actually make "fellow" in particular a bit more cool/casual, especially since it is a rather ambiguous term anyway and there are many kinds of fellows working on many levels out there. All it reliably seems to connote a learning environment, some degree of selectivity in participation, and less structure than a traditional school program.
