I favor editing directly, except in cases where a new position has been taken. Then I favor a second post, because this will allow us to capture the development of the ideas. This would include any important reversals or entirely new dimensions of the idea.
Putting all subsequent versions of the same post in a sequence would be a good idea; then people who come to one of the posts could see there were previous versions and/or subsequent versions. I wonder if some kind of tag or titling convention would be helpful.
