I wouldn't call that chronological, but otherwise you have a good point. This reminds me of a czech forum abclinuxu.cz I used to visit regularly using the following features: 1) dense list of discussions which you are participating in, with a quick way to find new posts there 2) one can optionally "follow" a discussion via email, this way, people sometimes noticed new posts in discussions which were months old Both features were quite visible, so most of active users were using them to some degree. Moreover like hacker news, the discussions were threaded, which is imho another feature which helps with long lived discussion. But compared to hacker news, it has much smaller number of users and lower volume of new posts (even at it's peak), so it's not clear how much would that help given the sheer volume of posts and users there.
