Each topic, on any forum platform has one main title.
Why must each post have the option to give it a new subject, or just repeat the same text hundreds of times ?
I dont see any good use of it and it enlarges the database with lots of useless-repeating text.
Their layout seems easier to read as after you read post1, you move your eyesight to the next text which is the next post, not the next post title/subject and then the post... Maybe phpbb4 could go for a layout alike theirs?
EDIT: Having the Repeated topic subject seems to cause seo issues too..
