What's amazing to me is how much we argue, considering how much we agree and how out of the mainstream we are. If you were to ask here whether it's OK for bikes to ride in traffic lanes, there would be no question of whether, and endless bickering about how.
I suspect if you were to ask the same question in the general population you would find more people who believe that Elvis is alive than believe it's OK for bikes to ride in traffic.
To answer the original question, yes, I feel I learn a lot here.
