Advertising always corrupts the goal of the search engine, which is to try to give you the most important stuff, not the stuff someone paid there to be there.
Tim WuIf you have a disease and suddenly start getting ads for cures for that disease and it's an embarrassing disease - all that kind of stuff it just gets into that zone of autonomy or privacy where you feel a sense of freedom to be who you want to be.
Tim WuI think, year in, year out, Google is starting to get worse instead of better. I think this is happening to a lot of the web companies, is as their demand to increase the payload they deliver in ads increases, they end up degrading and corrupting their own services. And you can see it with Google Maps, you can see it with Google Directions, where somehow Uber is, you know, always one of the options. And it's becoming exactly what they said was what they never wanted, which is a pay-for service where the highest bidder gets the best results.
