And there were versions of either finger or whois servers
(probably both) that had "continuous" options. I would still
claim that today's presence models are a significant change,
especially when they are adapted in a distributed
independently-operated server environment and that real-time
messaging is not. However, what this subthread demonstrates is
that they were conceptually an incremental change, not a giant,
discontinuous, intellectual leap.
I thought we all knew that.
