I have to admit, personally I find lurkers the most annoying thing in the world, if it was up to me everybody would be removed from #AG after 5 minutes of AFK, if you really need to send messages to each other and read them later, there is Email, Text, Discord, IRC, Whatsapp, TUS, etc...
I try to leave my snooper on as much as possible, so you usually see me there, but, at least i'm ACTUALLY at my computers ready to chat if someone messages, I admit sometime I pop out for 5-10 minutes and forgot to shut down though(apology for that).
