I haven't used Google search for much lately so I haven't really noticed this before.
Today while searching with someone over the phone, I would type in a phrase and before I finish the search phrase, Google auto completes and then drops me into the search results which are not what I was looking for.
I then have to go back up to the search bar and complete the phrase I initially started to type.
Have to say I'm not at all impressed with Google trying to think for me and causing me to do more work which is why I also think their so called "usage" is up according to that one engineer.
It is pretty annoying to say the least.
