I often wish this site did the profile field bits on top of the posts instead of to the left. Example here (please never mind their images in sigs, thankfully that won't be something we see on MR) It takes a little while to get used to but I think it looks really nice and makes pages appear much tidier when larger images are posted.
I don't care for this at all. Putting the profile right on top of the post text visually and cognitively distracts from the information presenting in the post. The icons also intrude on the message posted.
