This actually started (in a convo with Dani) as a simple idea of just upvoting comments made to posts, buuut I quickly got ideas for turning comments into a sort-of Reddit-style thread system, where comments could be collapsed so the original general idea of the forum thread could be viewed.
I'd also suggested a user display setting to collapse comment threads by default, but Dani brought up a conflicting idea that if someone made a comment saying some post was wrong or something, users who collapse comments by default wouldn't see it.
personally, while this is valid, the responsibility is on the user to expand the comments on the post
but to add, a following post explaining a mistake or such should be made regardless <_<
I'm sure people wouldn't do that, but I don't believe that should be a reason of detrament for such an idea
I mean heck, StackExchange has collapsed comments, and I haven't seen many complaints there
but anyways, I just wanted to suggest for some better functionality for this place :)
