@ Kioko
Thanks. I was beginning to wonder.
Personally, I dont like it... How are the SEO engineers and advert websites reacting to this - because I dont see the right hand column adverts...
And there is no guarantee I will click on the left hand side if I find what I want in the organic search results - which means the sites must have a really high ranking for particular from now on <to compete with the rest of the world> - if no accommodation is made available for blantant adverts on the same page as search results.

Lets wait and see if this works - because as I can see, commercial websites are now hidden in hierarchy on the left; how many will be patient to follow the tree ?? i.e if they get what the categories are for in the first place.
On the upside, it will reduce spamming <for a while>...
