Your example indicates you don't get it. You mention responses "from yesterday". That's not going to fly in an application that's real time that requires staff to keep the conversation open. You're describing a ticket system, I'm describing a live chat system.
I said "in the real world" as opposed to abstract talking about an application; in the real world a staff member would be stuck waiting for the response from this user where you're trying to keep the conversation going despite their sporadic connection. I guess I could have said "in meatspace" or something.
Links to explanations of the topic being discussed is of course incredibly insulting. Come on.
Anyway, whatever man. You are not pleasant to talk to so I'm done.
In the real world, network links go down all the time, even if just for three seconds.
As for etiquette... I politely explained how I see things different from you and provided a couple of links for reference. You immediately called me "condescending", "incredibly insulting", and "pedantic".
If you want a pleasant conversation, that's not the way to do it...
If a couple of links to articles is "incredibly insulting" to you then you shouldn't discuss stuff on the internet.
