The line that shows the links to other crossposts should add a (#comments), if there is any, after each link.

Some links get crossposted to multiple communities but I don't know if any of these posts have any comments and it's tedious to check them out one by one, and in my experience most of them don't have any comments which discourages me from checking them out.

Also crosspost links could be in order of comments.

Another idea: instead of (#comments) it could be a different color or some other indicator.
