Simple idea, really. In fact, so simple that I'd be very surprised if it wasn't suggested before this. A SuperSearch for "last modified node" turned up nothing relevant in several pages of results, with nodes dating back to 2004. It's quite possible that other search terms would produce what I'm looking for, or that I overlooked a relevant node. In which case, I ask forgiveness, for it is Monday morning.

In any case, I've been seeing nodes that have been updated by the author after other replies were provided. This frequently makes the replies confusing. For example, a monk suggests "on line x you need to change 'some code' to 'some other code'." Except that the node being replied to already has 'some other code'. Did the author update? Or maybe the monk replying misread? I can't tell.

So I'd like to see a small note added to indicate the last time the node was modified. I am not suggesting that the site keep a revision history or anything complicated, just a time stamp. Perhaps added to the information containing node creation:
"on Mar 14, 1592 at 06:53 MST ( #xxxxxx=monkdiscuss: print w/ replies, xml ), last modified Mar 14, 1592 at 07:53 MST"

I know nothing of the underlying codebase or how node information is stored, so I don't have any idea how complicated this change would be (i.e., does the database have a field where two dates could be stored, or would it require a revision to the whole shebang?).

Feasible? Unfeasible? Pointless? Best idea in the world? Interested to hear your thoughts on the matter.
