Looks to be happening soon on Chowhound - but it's just pictures without any text as to what is changing.
Could Jacquilynne or another Mod let us know what's going on? Are you just amping up the size of avatars and the ability to share on FB or Twitter?
I've posted information about the new design here: http://chowhound.chow.com/topics/880677
The screenshots that you see are a preview of the new board and thread pages. When the changes go live next week, we'll also be releasing a video that explains the features of the new design in more detail.
