Via The Browser an excellent account by Stephen Levy at Wired on how Google just keeps getting better. By using Google itself:

Google also has a larger army of testers — its billions of users, virtually all of whom are unwittingly participating in its constant quality experiments. Every time engineers want to test a tweak, they run the new algorithm on a tiny percentage of random users, letting the rest of the site’s searchers serve as a massive control group.

There are so many changes to measure that Google has discarded the traditional scientific nostrum that only one experiment should be conducted at a time. “On most Google queries, you’re actually in multiple control or experimental groups simultaneously,”

As for my favourite subject – me – I do not make it into the top Google pages if you search merely for Crawford.

But if you search for Charles Crawford, on page one of the Search results I wipe the floor with the myriad other Charles Crawfords out there, although our old friend the Abandoned Bunny does also sneak in. Almost the same on Bing.

Still, if you search Google for controversial former ambassador Craig Murray sweeps home. Fair enough.
