If your greed or need requires 'fixing' your post, I
won't object. However ...

All the motives that would have you hide the act of
revision are beneath you.

If it is important enough to change, it is important
enough to note the change. Do not short-change those
that paid attention to you in a timely manner.

The humbling experience of seeing your own words as
less than they should be, will increase the quality
of your posts. Or may inspire you toward silence.

The humiliation that others might heap upon you
will not be so good for your soul unless you let it.
This is not always easy nor always appropriate.

The coldness, the coolness, the warmth, the heat,
and the fire found in responses will show you the
people behind the screens.

Every post could be better.

This post could be better shorter.
