In response to pg's essay on ambitious ideas for startups, Matt Cutts said: "Paul's #1 suggestion is reinventing search. I happily welcome competition in search because it keeps us on our toes, but his #2 suggestion resonated with me more: reinventing email."

Today, they said that, for first time, they are releasing a video about what they do on a search meeting. http://insidesearch.blogspot.com/2012/03/video-search-quality-meeting-uncut.html?m=1

I wonder what pushed them to post this video. It's not even very informative, it talks about searches of N-grams and spell corrections, it seems more like something to show how advanced the changes they make are.

I'm sure watchers must have thought that search is so advanced and hard seeing that video that they might give up. It must be so hard to catch up with them ;-)

Maybe google is afraid of a plethora of YC (or not) startups trying to reinvent search. One may succeed.
