My random thoughts on a way to keep track of this: 1. RSS feeds where the link goes to the hn thread instead of the linked page? Though not everyone uses an RSS program integrated with their browser and opening an external program to keep track of HN threads isn't exactly good UX. 2. Keep track of how many comments were made when someone first views the thread and if there's any new comments, change the link color back to black instead of the grey that would show that it was already viewed. 3. The star icon previously mentioned. Have items automatically decay from the list after a certain amount of time (or time without a comment) to keep it clean. Upvotes can/should double as favorites since hn keeps track what someone voted for already.
