You weren't available all the time then. It was perfectly natural to assume someone wasn't at their computer and that was perfectly ok. It wasn't necessary to give status updates that you would in fact be on time to meet like you said you'd be, things were a little more planned, and you'd call or SMS if really needed but mainly don't want to intrude.

Someone made the observation back then that 'the less you talk about "being online", the more important it will be'. Nowadays, because of IP-over-radio (smartphones) we're all basically online all the time (which has been true to a certain extent for a while with (dumb) phones and SMS/texting).
But it goes further now with many more ways of interaction.
