I realized today I have never once used a threaded (or hybrid) view on any forum I have ever visited unless just checking it out to see what it was and immediately switching back.

I understand the indented reply comment systems you see on some forum system (check out the forums at Drupal.org for an example). Those types of systems allow you see who replied to whom while still in a mostly linear format...
But threaded view that shows only 1 comment at a time or a single group of comments seems straight out of 1990, back when pages took forever to load and we had to walk 15 miles in the snow every morning to get to school.

What do you say? Have you ever used a threaded or hybrid view? Do you think either still serves a purpose with today's modern Internet?
