I recently had a comment on a post that I posted about a year ago. Now, how I thought Ask Ubuntu works was that you answer, and your answer stays. Even if it is three years ago, you don't need to edit your answer (no matter how bad it is). Of course there are cases where links change and you need to change them. I didn't think suggestions (like the one on my answer) would come (a year later).
My question is, is it good practice to hunt down those old posts from myself and improve my (bad) answers (since I know a little more than when I joined Ask Ubuntu)?
Maybe even posts from other users too?
