We’re probably the same age, and I definitely see people matching that description.
Just to note, there’s also a decent number (most I know?) that went almost the opposite way:
“online” was a novelty but also the only place to share their experiences and participate to their community. With a group of friend we pestered the local com. company for broadband and were among the test group when they decided to start, and spend a crazy amount of time on IRC/ICQ/usenet.
I recently met again with some of the old friends, and our facebook accounts are stubs to keep our name. We’re still on other anonymous SNS but it’s clear we don’t want to share more than needed, and don’t want to spend too much time on it overall.
Basically now that “online” can be used anytime from anywhere, there’s no need actively seek it and novelty is gone so we’re more restricting what we do there.
