Just to be clear: you can do this with basically all social media, but I think it's an interesting discussion to be had that these services exist (and have specific detail, such as the comments[1] or FAQ[2]) one. This isn't a knock against any of the HN staff, but rather about how discussion can be paid for and shaped.
