Why is it necessary to KNOW when the last time a mugger edited an answer? Are we gonna cheat and change the answer? Silly.

In the event of a court case - if someone tried to sue JA over something said and later edited - the fact, the content of what was changed, and the timing of the edit could make a difference.

I find it helps to tap in four spaces after the end of the answer. That way the notice of the edit doesn't impinge on the answer.

I agree, it is needless and annoying. 

If I post something and you respond to THAT post and then i change my original post, your answer may not be relevant once it's changed.  

  I agree, I despise that notification box so much that I avoid editing my posts at all. Instead, whenever I post a typo or for any other reason need to edit, I prefer to delete the post entirely and rewrite it.
