But information treatment is only one priority these days... simplicity is one of google's major advantages. Aside from the little one-liners about google services, their home page is almost as empty as it always was and loads just as quickly. There's one box where you can enter whatever the hell you want, and Google will usually find, decipher, or correct whatever it is. Most people don't even realize they can enter search operators into the box to get more specific (I'm a frequent excluder of words in google), and Google probably likes it that way.
You don't have to explain one single thing about them, their page, or how to use Google in general, even to some without any computer knowledge, because it is so incredibly fast and simple. If they only offered an advanced search page, that simplicity would be gone. Even if you didn't enter anything except in the top search box, you have still lost that "empty" simplicity that is Google and replaced it with power features which, for the most part, aren't even necessary if you use operators in the search. I like Google's advanced search feature, but I'm glad they offer the simple one-field search box on their homepage; it's part of the reason I've stuck with Google for so long (aside from the fact that the results I get from Google are often leaps and bounds more relevant than those I get from other engines).
Not only is Google the fastest (at searching and displaying pages) search engine I have ever used, it still manages to be the most powerful. What I find on the first page or two in Google is often what I'd have to browse through pages of results for in other engines. I am also a fan of the fact that when they add new features and services, they generally do it behind the scenes and leave their core service alone (at least seemingly). That consistency is great in a world where so many sites are trying to be the be-all end-all of Internet destinations and are just adding layers and layers of complexity and often useless features. Go Google!
