How to comment when I arrive late at a post with many comments?

I usually only read LW every day or two. I'm also in the GMT+2 timezone, so US people mostly comment while I'm asleep. So when I reach an interesting post, like this one just now, it already has many comments. I really want to reply to some of them and to the post itself, but first I need to read all of the comments and internalize everything that has been said already, or I risk repeating what others have already pointed out. For a post with hundreds of comments, this is a lot of work.

I would welcome any tips for being better, or more efficient, at this.
