Thanks Dave - I was reading it over the weekend - from your post on twitter.
At the moment, as a search user I'm just annoyed, I have to keep checking if its turned on personlisation or not. And given the write ups on the various Biometric assessments (which I've doubt they're using - the cookie seems adequate and is probably related to any signed in accounts (as they don't give away secrets to other users - just to Google who knows thats one of your PC's) - I still don't "trust" the results.
I'm sure this isn't a problem for average users (ignore truly is bliss).
I think vanity SERP's were always just that. We all know 60 - 70% of traffic
can come from longer search phrases - if it's too narrow, then you may have very little content. I have have 8/9 keywords in a search phrase - using minus and other paramaters.
