I would indeed enjoy a built in rss feed for replies on topics / threads I have found important. I'd also like a link to a wiki or something that could be updated with more replies and new information about things perhaps also including links to other hn threads that have referenced / linked to the same. So continued discussions could occur and extra info combined. rss feed, email notification, sms maybe.. Not all threads, but some are of high interest to me for sure - and checking the myprofile-comments for new info is tedious, though used many times for me.
