I am ashamed. My Meta rep has recently surpassed my SO rep. Even putting a (relevant!) Shakespeare quote into an answer on SO couldn't do anything about it.

That's why I looked for one of my old Meta questions to put a bounty on; I chose this one.

I will give the bounty to the best idea/solution (my choice) offered to solve the problem raised in this question. Humor is encouraged, but I'm still looking for a real suggestion. Mock-up screenshots would be nice; freehand circles will be well-received.

The second best will receive a 1024x1024 hi-res version of their unicorn avatar.

PS: I'm not making this CW so all answerers can still get rep. I don't expect 50 upvotes on this question anyway.

Original question:

I just edited this question to clarify, or basically, make it readable. Shortly after I was done editing, the original question was there again.

The asker had made a change to their question, and this edit was based on the first revision (probably because they hit "edit" before I had saved my update). Because the question was very much unreadable, it was hard to see what the change was exactly. The automatically generated edit log message stated "deleted 3 characters in body", but it was hard to see what exactly those three characters were.

So I viewed both sources, saved them to text files, and did a diff locally. Turns out they had just removed a newline and turned "???" into "??" in one case. So I new I could roll back to my clarified edit without losing anything important that the asker might have changed.

I can't imagine this to be an uncommon problem.

It would be nice if it were possible to

  • either see the difference between two user-chosen revisions in the edit history,
  • or at least see the diff between a revision R and the revision that R was based on.
  • I'm very close to my SO rep also...

    You don't know anything about having your Meta rep outweighing other rep.

  • @Marcel stackoverflow.com/questions/2239516/… -- it's deleted, though (the question was a dupe), so you'd need 10k rep to see it.

I agree with Jon in that it might not be the most frequently used feature but the usefulness when it is needed could be big.

Was just thinking about this again and I thought a UI where you could check a couple of boxes and send those two revisions to the diff engine could do it, similar to a commerce site's "compare these products" UI.

Diff Revisions Selector http://www.sqeq.com/image/MSO_DiffRevs.png

Then there could be a new view that would show just those 2 revs side by side, with the changes to the most recent rev highlighted like in the existing rev view.

    Nice! The "check two revisions to compare" is pretty much how Wikipedia does it. But I hadn't even thought about how to present the revision diff -- I like the idea. So here's the lineup: +1 for mockups, -1 for Comic Sans, +1 for FH circles, -1 for stealing from Wikipedia, +1 for the presentation idea, -1 for bounty whoring, +1 for stealing from wikipedia, -1 for Comic Sans, +1 for bounty whoring. Total: +1

  • @balpha This is the ultimate bounty whoring question :) I actually just felt bad for putting that lame (now deleted) jQuery joke in... Now off to reset Balsamiq away from the evil Comic Sans.

    These mockup images are now giving 404. We can inline images in posts these days so you might want to edit your post and do that if you still have those images :)

Nice idea. I suspect it's more of a pain in terms of designing a UI that doesn't get in the way when you don't need it (i.e. most of the time) than in terms of the diff... clearly all the information is already available in the database, and the diff engine is there.

I can only think of a handful of times I'd have wanted this, but in those cases it would have been very useful. Of course, the next step is to do a guided "merge changes" operation...

    Agree on the difficulty of the UI implementation. Maybe two different sort orders (by revision number, and a tree-like structure using revision parent/child relationships)? BTW, I don't even know if the parent revision of an edit is actually stored in the DB.

  • I'd just allow arbitrary diffing - usually it'll be obvious (to a human) what you want to diff against.

If you receive 55 upvotes, would you do the same on another question and so on and so forth, generating a rep inflation no man has ever seen before, in some kind of perpetual motion machine (understanding by motion an 'exponential growing of reputation') crashing the system?

That would be so cool.

    I doubt I'll come up with enough questions to do that with for creating a singularity.
