What I would love to see is two links off of Newest Nodes - the one we
see now and Head (or something similar). I often find myself clicking
on a link, then not even reading it until I click on the head node. I
like having context when I read and I can't keep the context of the 10
threads I'm reading throughout the day straight.
I seldomly try to keep track of a thread. The UI of Perlmonks makes it
so much harder to do than for instance on Usenet. Perlmonks doesn't
give you a way to keep track of what you have read, and what you haven't
(well, unless you read at most 40 posts, and vote for every post you
read). Newest Nodes just don't do it.
Furthermore, people have the tendency of to not quote what they are
responding to. Which means that if you try to keep track of a thread,
you often encounter a reply that requires one or more clicks to parent
posts to see what they are replying to.
