Seeing this in the middle (as above) of the wide ads of another site and I like it and it would fit in well with the look of my sites. Wish this would go global or maybe Google could make it an option within My Account which we could switch on/off? With the vertical ads, they could give you the option to center the tags, i.e. Ads... at the top, centered, and Advertise... centered, at the bottom.
