The purpose of Reminder Bear is to go back to sites that will see some update in a week's time. It's not just for HN, you can use it on any web page that you want to be updated on. Most discussion on the web ends after a week, and if it's still going strong you can resubmit it to check next week.

Here are the things I've used it for so far:

    Forums that I'm not subscribed to

    Sites with comments that don't notify me of replies

    News stories

    Reddit threads

I also see what you're trying to do and albeit a thoughtful exercise, it seems that outside of a niche audience it wouldn't scale these days. There are just too many meaningless threads that will never die out there.

Good luck though.
