I probably don’t have the time, but where would I even find out about those openings?It's clear to me that for someone who is just organizing and attending competitions, you have a clear interest in inner WCA workings. Committee/team positions are constantly opening, and if you have the time, I'd highly recommend becoming part of one to become more familiar with what happens.
I do not advocate wholesale change. As far as getting people in who have no experience, how about this as an amendment to the proposal that Mr. Burton so magnanimously shut down: rather than 5 Board members elected to a one year term, 6 members with 2 elected every year to a 3 year term? Or some variation on that. Just something that would allow for the continuity that I think you are rightly concerned about while still opening the system up a little for some community accountability.
