Yeah. I created a thread recently that had over a hundred replies, but over time, each notification became a frustration because the notification link doesn't take me to the actual comment, just the first page. I'm not sifting through 10 pages to read an entire comment and see if it warrants a reply.
Experiencing the same "amazing UI but frustration experience that makes me check out" UX w/ firefish (fka calckey) as well.
