Comment by thebigshane

Private comments and automatically fold/collapse long/low-point threads and negative-comment scoring comments.

Optionally mark your comments as private for grammar/spelling/technical errors, way off topic comments and personal requests.

I think graying out works for comments scoring 0 or maybe -1, but beyond that, might as well fold/collapse them.

I also think something like xkcd's Robot9000[0] would be useful to prevent some clutter like "me too!", "awesome!", "Thanks"
