What do you think about Post-edit improvements - whilst keeping the original?

I am all about efficiency, and also creating and using references more efficiently. As such, it would be nice to reference your previous fitting answer to a current thread, but be able to add to the previous (say beneath it after a separator etc). Would add a lot of value to older threads.

You could also see how your answer/knowledge improved over time.

Side ideas, being able to re-edit it and showing that, but for the viewer to easily be able to parse the original answer (that got all the lurve…).

I also tend not to answer if I have already given a similar response. But it is harder to easily link previous responses through fluther.

Discuss.
