MTO,
There's no arguing with the coolness factor []/w3timages/icons/wink.gif[/] You have made the post meta data dance !!
Of all your examples, I like the last one best. I think, however, that I prefer the "posted by," post date and time, IP, and user info at the bottom of the post. When it appears immediately below the post header/title, it tends to lead to some temporary visual confusion on my part, not knowing whether the post header is the beginning or the end of a post.
Since you have already invested several hours learning how to move data around the display. How about giving a shot to what I am suggesting so we can see what it might look like?
Thanks for posting your work. I can see that you really did spend a lot of time on it, and my comments in no way diminish the "coolness" of it []/w3timages/icons/smile.gif[/]
