Some suggestions. First, if you've typed longer than a minute, make a backup copy of your reply, even go so far as to compose it in a separate text editor, then paste the result into HN. Second, if you encounter the dreaded "link expired" message, select all (Ctrl+A) then copy (Ctrl+C) the content of the entry window, then press browser refresh, then paste (Ctrl+V) the text you just copied. Then click "Reply."
(Trick question, R3 only had ctrl-insert etc OS/2 shortcuts!)
In any case I apologize my paste-buffer foibles denied you my three paragraphs of immense wisdom regarding the good & bad of an obsolete end-user friendly distributed database system that went out of style a couple decades ago.
Lowest common denominator, as they say. When I encounter someone who loses his content on the HN interface, I make some simplifying assumptions. :)
In any case, Notes ended up sucking, anyone who saw what happened can toast to that.
