It’s nice to be able to see the diff between any 2 adjacent revisions (revs 3 and 4, or revs 8 and 9), but this is really insufficient when a post has been changed substantially over time, or if someone makes a bunch of small changes saving each as they go, especially if they multiply revise those changes.
I very much need to be able to see the diff between, for instance, rev 3 (which I produced) and rev 9 (which is the current, having been changed by multiple edits by one or more colleagues) … because it doesn’t matter who made what changes, nor when (especially if later intervening edits undid some earlier edits); it only matters that I can see what now differs from when I last touched the post.
Wikipediaは、ウィキを編集する人々が慣れているものなので、先行技術を探すのに適した場所です。Help:Page history - Wikipedia には、Wikipediaの改訂システム全体を歩き回るビデオがあり、それは非常に強力で、難解で、圧倒的でもあります。ウィキトピックに大きく依存し、バージョン管理が優先されるサイトでは、これを再現することが、貢献したい人にとって興味深いプロジェクトになる可能性があると思います。プラグインになるでしょうか?
