I guess I've always posted only on HN and not individual blogs, mainly because I hate to spend even a few seconds signing in to these various sites. The disadvantage is that the bloggers might not actually see what's said here; but I've found that a surprising number of them do. (And "threads" at the top of the page shows any replies to your comments here.) Some blogs accumulate inflammatory or vacuous comments, which is another reason it can be nice to focus only on the discussions at HN. :)
