FWIW, Discourse can be configured to be push or pull based on a personal level. Not only on a personal level, but you can control at at the category (similar to different lists), tag, or individual topic level. I’ve responded to you on Discourse in more detail, but I find the level of control quite nice in a way that lets you choose push or pull based upon how much you care about a particular topic.
