Random question... is hn_throwaway_99 your main HN name or you still maintain a main account? I know a lot of folks use a throwaways for controversial stuff or for 'anonymity', but it seems yours is quite prominent.
Heh - short of it is I originally created this "throwaway" account years ago, I just forgot to throw it away. The initial impetus was yes, I was commenting on something controversial, but then I just forgot/was too lazy to switch back to my original account so I just left it.
