diberry - I have no idea, it doesn't happen for every search ( in my neck of the woods ) but enough times to be annoying. I have a funny feeling it's either a by-product of one section of the algo or the 'whitelist'.
[ The 'whitelist' may not be an actual list ( although I think it is ) but just a group of brands or favoured sites that heavily meet the algo's requirements, possibly by design. ]
Removal of domain crowding would please a lot of people, including me :)
