I asked Amit Singhal, Lead of Google Search, about how changes are evaluated, and he answered that they have the entire web in a sandbox that only their engineers can see, and their engineers can take their new algorithm and see it change millions of queries. If it works, they send it to testers, whom they pay, but they don’t tell them what they are testing. Then they take a tiny slice, one per cent of their users, and expose them to this change. They measure things such as where on the page they click, when they click higher – that’s good for them.In my opinion, there are many factors which indicate that the algorithm has improved or become worse, like:Search Exit : The number of searches a visitor made immediately before leaving the site. Note : (search exit here is like bounce rate in any page)Search Refinement : the number of times a visitors searches again immediately after performing a search.Time After SearchPrecision : is the fraction of retrieved documents that are relevant to the searchRecall : is the fraction of the documents that are relevant to the query that are successfully retrieved.Search Depthand other.You can see more details about that inside Evaluating Search Engines presentation.Evaluating Search Engines

In my job as an innovation advisor in Sweden, we often conduct a form of presentation evaluation called “Value Creation Forum”, which requires a panel of four judges who wear four different, funny hats to indicate the perspective from which they will be judging an entrant’s idea and presentation.It’s a bit like “Dragons Den”, just funnier.There is a green hat, who talks first after the presentation has finished, and points out everything positive about the concept shown. Then there is a red hat, which tries to be constructive and points out ways to further improve the concept, a gold hat which talks about feasibility and the business perspective, and some silly eyeglasses which represent a consumer or member of the general population.These four roles are assigned anew for every presentation, and this usually happens with words like these:“Tobbe, you’re the green hat this time; Pelle, red, Chris gold, Hildur, the silly glasses.”Last time we ran that event, we had a new, British colleague as moderator, and his way of saying it went more like this:“Tobbe, would you mind taking up the role of the Green Hat, this time, please; Pelle, the Red Hat, that would be very helpful; Chris, it would be great if you were to take on the role of the Gold Hat; and Hildur, the role of the consumer, as indicated by wearing the Silly Glasses, that would be very helpful. Thanks everyone. So, we continue now with the…”It struck me right there and then how very differently the British communicate, compared to the Swedes. There is this endless stream of polite, mellifluous diction, taking care of all diplomatic eventualities, almost like Japanese.I just grinned to myself and enjoyed it while it lasted.

In line with the other answers:It's been built on the space previously accupied by the old gare Montparnasse: it was a huge real estate opportunity, very beneficial for the SNCF (the national Railways company),Towers were very trendy at that time (think le Front de Seine and La Défense) and were thought a rational answer to real estate problems within Paris,That area was derelict and in dear need of refurbishing...Think of it as a bad answer to a good question...As for destroying it: the present evaluation for deconstructing it runs around 1 billion Euro...
