>This is the UI that I see after the introduction of the News Feed. Does everybody else see the same?

That would be pretty much it, assuming we do not see the left part, because of the way the image was taken.

Newsfeed was introduced in spring but not widely broadcasted. It is still an option presently and you can adjust your account setting to preserve the previous interface for a while. We will have another version soon based on the comments received since spring, and as per the objectives of the product.
