The comment links in the "activity" and "responses" tabs of the user profile now work correctly when the comment would be hidden behind "add / show n more comments". This is great! However, it appears that we have comment links only for comments to answers, not to questions.
For example, on my "activity" tab I see the link Comments that fail to post start the “You can only comment every 5 seconds” timer to a comment @Matthew (timestamp 2011-09-26 14:23:23), and it takes me to the question. I'd expect a link that takes me directly to the comment, like this.
(It actually took me some time to figure out what's happening; apparently I'm not the only one confused by this.)
