a) never really used a compass on a bike, it might be better comparison in situation where its more commonly used. (or maybe in my tiny country things are different!).

b) a compass without a destination is just amplified wandering too. you know your direction but not the destination.

now i know thats an unfair way to read it perhaps considering there is an entire article but these 2 things jumped at my inner-**** and caused it to break my concentration and stop reading.
