I just received my first email notice from notifo and it's still not clear to me when I will (and will not) receive email notices at HN: Will I get them ONLY when someone replies to a specific post I've made? Will I get them when someone posts a reply in a thread I've created, even though the reply is to someone else's post instead of to mine? Will I get them when someone posts a reply to someone else in a thread that someone else has created? These are just a few of the questions that remain unanswered until I do some more testing ... but my current suspicion is that notifo cannot notify me unless the post is a direct reply to one of my posts. If this is true it means I will NOT get a notice -- even in a thread I created -- when a reply is made to someone else's post. And if this is the case it will fail to notify me of all the HN activity I want to be notified about. :(
