I think all of this is a question of taste (correct word ?)
ie: I wouldn't have sat the edit and quote button at top, as both are used after reading the post, not before, so it makes more sense to see them at bottom. Also the creation date takes a poor place at the bottom : it is much more a subject relative info than a signature relative info (when you write a letter, the date comes first, not last). Post subject, although it is a really important information, still remains in small size : it would have been more appropriate to have it bold, and in the text size, and without the "Post subject:" mentioned on each post : I think a reader is smart enough to get to the conclusion that a title may be considered as a post subject

. Anyway, hopefully the template system let us designed them as we prefer, so that's not a big deal
