The case for the /usr merge

You make it sound as if sjj magically should have known that you were going to come back and correct your error, and that it was very impolite of him to have done so before you did.

People correct each other not only because they're smartasses, but also for the benefit of others reading the discussion, and for guiding the discussion away from the wrong direction.

Perhaps you are proposing that before we correct anyone we should:

* check when this person was posting

* if it's less than a minute, wait a minute, check again whether they posted a correction

If so, I propose you lead by example. :)
