I should add that HN doesn't like brief, content-free "+1" or "this" comments, but a few sentences explaining
why you liked a comment, and why it was exceptional in some ways, is almost never a problem, and are often greatly appreciated.
For example, you'll note that choppaface's comment has not been downvoted below 0, and probably has a few upvotes.
By the way, I also very much enjoyed your comment.
