Talk About EDITS - Trackable, Transparent and Nondestructive

There’s been some talk about the future addition of an ‘Edit’ feature.

Editing can change the tone and entire meaning of a post or comment, also changing the meaning of associated comments and reactions.

When implemented, I feel all edits need complete transparency. I think there should be some visible history available. There are a couple of ways I think this could be implemented:

Have a strikethrough system for omissions and some way to identify additions, like underlining or a change in text color.
We could also have a clickable post history feature with some changelog of sorts. If a post is edited Digg should mark it as so, and you could click on that ‘edited’ label to show the history of all changes.

I like the second idea better in case more than one change or iteration of changes is made to something. It provides complete transparency.

There wouldn’t need to be any notes about why something was edited (edited for clarity or spelling) - anyone can look and see for themselves what changes were made.

Maybe someone has a better implementation in mind. Perhaps a combo of both or something else.

Thoughts or ideas?
