This is very inappropriate. Dissenting opinions are fine, but this is the worst way to go about voicing it.
Edit: Or rather, as of this evening, click on the comment's timestamp to go to its page. We decided to play with dropping "link" and just hyperlinking the timestamp instead.
So the only change as of yesterday is that now, to go to a comment's item page, you have to click on the timestamp instead of a link marked "link". If people find this confusing, we'll put "link" back. Fortunately, it's the kind of thing we can measure.
