I've posted this in the SEO forum as I guess it is applicable.

This effectively means that you won't get exact keyword reports through analytics when the user has gone through HTTPs (which is when they are signed in, as most are nowadays with Gmail, Google+, Buzz etc.).
Rather you'll simply get a top 1000 referring keywords list from webmaster tools, not analytics.
What a pathetic move, why remove that data, it is doing no one harm and helping webmasters tailor content to better suit the users queries - something in both ours and Googles interest!
