Here're my running notes PC Forum's chat with Google's Sergey Brin
Some day, you won't be able to email a query to a friend and rely on her getting the same results — that's the downside of customization. If you take the average Google Query and give it to a librarian, 80% of the time, he'll be able to find the answer without any further customization — they don't need to know how old or young the questioner is, or what her zipcode is.
But that does mean that 20% of the queries could be improved through personalization. We need to figure out how to introduce that fairly complicated technology quickly and without it being confusing.
We do Google News. It's great, but we don't know how to make money off it. On the other hand, after acquiring Deja and turning it into Google Groups three years ago — a purchase we thought would just give us great content and no money — but now we're running ads targeted on the content of the message posts in Google Groups. That's good for the advertisers and for users.
