Sounds like RSS.
Nice work, and looks pretty, but Feedly scratches this itch for me almost perfectly. And it expands well beyond Reddit and HN.
The only better solution would be if I hosted my own and used an open source app. I'll get around to it.
When I tried rss with Feedly before. I wasn’t getting blog post comments. I don’t think reddit/HN comments either but could be wrong there.
You get the title which is a link to the submission, a picture and a link to the comments. I'm on Android so hitting either opens a webview (powered by Firefox) with an X in the top left which leads back to feedly. I also have scrolling past a submission set to mark it as read.
Admittedly something which handled unread comments and notifications for replies could be more engaging, but I feel like I get enough HN as it is and I want to remain somewhat productive.
