This paper does a good job relating OT and CRDT as the two major approaches to collaborative editing.

For anyone interested in this topic, I'm publishing a new theory on this called Collapsing Time Machines: https://braid.org/meeting-111.

Not so sure about that. Undo in OT seems simpler to me than undo in CRDT.

Just want to say- very pleasant blog from a typographical and design standpoint.

Edit: Looks like you made the font yourself, very cool.
