I use this tool, and its realy great! It keeps me connected in a slow velocity way to a conversation.

This sound a great tool too. Thanks for sharing.

Note that hnreplies asks not for a comment ID, but for your user ID. You get notified when someone replies to you in any thread whatsoever. You don't have to continuously monitor specific threads. That's the point.

Say I'm involved in 17 recent threads, in any of which there can be new replies. Do I have to bookmark 17 hntoast URLs and monitor them?

Or what if, today, someone replies to something I wrote in 2019? [Edit: that won't be possible; HN doesn't allow necroposting!]
