I have made an impressively insignificant contribution to Wikipedia

Much has been said and written about Wikipedia. Many people
contribute many hours to this noble cause. I, on the other hand, have
contributed one tiny factoid to this vast web 2.0 body of
knowledge.

  Bonham's Drum Pedal Squeaks on Ten Years Gone

I slept well that night, after making that contribution, knowing that
I had made the world 0.00000000000000000000001% better.
