Making it easier to see what 'comments' on SE are about is IMO a great thing too.
I just don't want to get rid of 'comments' as temporary post it notes, that are directly attached to a post
(because I feel a comment saying 'look, broken window' is useful to more people that just the OP that needs to fix their window,
it's also a bit of a warning sign if you're trying to learn the norms of a new site). I also don't want these collaborations to hang around forever:
If they're finished, clean them up and reduce noise.
