I was thinking perhaps there could be an "Updates" section in Newest Nodes?

Geez, then every node of mine would create around five entries in that section within the first minutes after posting (until I've finally finished all my spelling corrections and rewording attempts)...  I'd seriously have to reconsider my posting habits, if that section were to happen :P

Update: in other words, if so, please let the poster decide (checkbox, or so) whether it is a significant update that you would normally mark as such (like this one).
