When comments on a post exceed the limit some are hidden, currently this is based on popularity. There are already some suggestions relating to showing comments chronologically instead (eg here and here) but I have an additional suggestion: show the N most popular plus any intervening comments made by users who are addressed with @user in the ones shown.
For example, on this post, Michael Borgwardt's highly upvoted answer has five comments shown and a link to see six more. One of the five, by ruakh, refers to an earlier comment by @ArjunShankar.
I would therefore like to see ArjunShankar's comment(s) included in the shown comments rather than the hidden ones.
