| > I wish someone would collect stuff like this and write it down in some sort of "oral history of collab editing. I'd be very happy to contribute to this if someone wanted to do some storytelling. I also interviewed Kevin Jahns, the author of Yjs several years ago to get his take on how Yjs works and how he thinks about it all [1]. The conversation was long but I very much enjoyed it. > This is only our own experience, but what we found (and the impetus for part 1 of this series) is that almost 100% of the time, when there is a direct editing conflict, users interpret the results of the dominant CRDT and OT implementations as silently corrupting their data. That's not been my experience. Have edits been visible in realtime? I think about it as if there's essentially 2 use cases where collaborative editing shows up: 1. Realtime collab editing. So long as both users' cursors are visible on screen at the same time, users are often hesitant to type at the same place & same time anyway. And if any problems happen, they will simply fix them. 2. Offline (async) collab editing. Eg, editing a project in git. In this case, I think we really want conflict markers & conflict ranges. I've been saying this for years hoping someone implements conflicts within a CRDT, but as far as I know, nobody has done it yet. CRDTs have strictly more information than git does about what has changed. It would be very doable for a CRDT to support the sort of conflict merging that git can do. But, nobody has implemented it yet. [1] https://www.youtube.com/watch?v=0l5XgnQ6rB4 |
Sorry, I see why this was confusing. What I'm saying is that because users perceive the results of OT, CRDTs, prosemirror-collab, etc. as data corruption, they require presence carets as a UI affordance, to steer them away from direct edit conflicts.
If you can't have presence carets, yes... likely best to have a diff view. And in our case, we use git/jj for this, rather than CRDTs.
For the "history of" stuff... in spite of the fact that we have our disagreements, I actually think it would be very nice to have Kevin and everyone else on the record long-form talking about this. Just because I am a non-believer doesn't mean it wasn't worth trying!
