It was interesting to read The Guardian's interview with Sergei Brin today in which he expresses concern about commercial interests and governments damaging some of the principles that have made the web so successful, and Google so successful at searching it.
I was lucky enough to meet Sergei years ago at the first Super Nova conference in Palo Alto just before their IPO. We were each allowed to ask him one question. My question was what he was going to do, being an American company with, at the time, most of its servers on American soil, when the US Government asked them to index some bits of the web better than others or in some other way tried to control their activities.
He didn't really have an answer but from his comments in The Guardian interview it would seem he has been trying harder to come up with some recently.
