I’m a little late coming to this thread, but I only discovered the Discourse from an email posting today.
So far, in using Discourse, I have one significant complaint: all replies are linearized. A significant advantage that mail lists and Reddit both have is that the replies are organized in a tree. As soon as I see a sub reply that I’m not interested in, I can collapse that, and go on to the next reply that is not a reply to that one. With Discourse, I’m just presented with a long list (dozens and perhaps hundreds) of replies, and don’t feel there is any of figuring out what is meaningful in that.
Perhaps Outlook and Gmail having removed this tree-view has made people not expect or be aware of it, but for me it makes the difference between a forum I can follow, and one that largely gets neglected.
Possibly related, Discourse’s notion of what I’ve read also seems unusual. In the “new” list, they don’t seem to get marked as read the first time, even if I’m careful to scroll through all of the postings.
Is there a better place to be discussin Discourse than a comment at the end of a long thread?
