This piece is a year old (heck I might have even posted on this before) but it came up during extended searching on LORs vs. LCMSes and I thought it interesting because in describing the ‘evolution’ (mostly just history) of LCMSes it gave me some more context for why we have all these LOR initiatives that seem to be relatively isolated from the evolution of LCMSes and learning authroing tools. – SWL
