Sometimes I open a thread that contains read and unread posts and I don't know what posts I didn't read.
Reason for this can be browser window height and resulting incorrect #id-jumping or just a browser fail or me opening many thread windows/tabs and scrolling in read ones and forgetting which ones contain unread messages... So basically software and human failure.
I think adding "► " in front of the post date would be a fairly subtle but also enough notable way of indicating new posts.
that's a good idea. i like it.
