ask the only replies that matter (at first) are those at the top of the tree (the roots of the comment trees, per graph theory).
It is mildly annoying (specially on mobile) to scroll past 20 replies to the first comment, then another 15 after the second one, and so on.
I propose folding replies by default, or rather if the user reading the comments has folding enabled in its own settings. Folding replies is implemented already, just not by default.
What do you think?
