When I am following a thread, I'll get an alert that says "ABC and 72 others commented on XYZ thread", which is fine. But when I click on the link, it takes me directly to ABC's comment. But if I want to read all the comments, I have to scroll back to the top of the thread and click on the "96 new comments, click on the first one" link.
I think it would be better if the link from the Alert took me to the first new comment.
Plus... it's free!
