The first update is out! I've updated how replies are styled. They no longer look like top level posts. They have a bit smaller text and gray background. This makes it easier to distinguish them when scrolling through the list of posts. Enjoy!
New reply format
Replies can go forever deep right now. Waiting to see what happens before I code anything to handle it. Likely we'll have some sort of collapsing.
I agree with you about reply/top level post distinction on the "last topic" area of the board list isn't the best. I'm pretty much waiting to see how people use replies right now. Are nested replies typically tiny things, or are they going to be substantial posts.
The url for the topic thought should point to the latest post and not the top of the topic, that's a bug.
You might want to figure out a different way of visually showing nested comments when you get to a certain depth, because the comments get pretty badly squished.
Was gonna mention this myself. So, uh +1 I guess? The indentation per level seems pretty extreme to me, could probably be taken down a bit too.
Not only that but there's padding on both sides: top-level posts should have padding on the right, and replies should have padding on the left only
Collapsing could be interesting. It seems like a lot of replies right now are well written posts and I don't want to hide them by default. But maybe it just crops the post to a few lines so you can get a preview. Discourse does replies kinda strange. A reply is both a regular post in the level of the thread, but also can be opened up from the post it was a reply to. There it makes sense to collapse to prevent showing it twice.
+1 for the ability to collapse, though probably not by default. When I browse Reddit or Hacker News (with an extension), I collapse posts / subthreads as I read them. It helps me keep track of where I am.
The state could even be persisted in localStorage so that when one returns to a thread later, one can start reading new stuff right away.
