I really appreciate the work Simon has put in but have to agree that there are some changes that I don't think have been for the better. My main issue is that with the old forum you could very easily see the latest comments on a thread and decide if you wanted to delve into it. When you did you went to the latest posts. Now you just see the original post and have no idea if the latest comments merit further investigation. I also think there is less information on the screen, even with snippets. The option to display 20 posts is fine but that get's lost each time for me as I browse with Chrome incognito turned on so the setting is lost. Not the forum's problem I guess :-)
The plus side is that editing with an iPad works much better. The messaging side is improved as well.
