I like that it's now widecreen, but it doesn't look like the actual posts are stretching (just the layout)
there is still a word wrap on lines longer then about mid-way through the screen, so everything is very justified to the left. [edit] Looks like this is only the case on posts made pre-widescreen perhaps?? weird.. [/edit]
I might recommend making it a little less wide then this, because I agree with Lord C on having to turn my head left to right (and I only have a 22" monitor)
