Why should users rave about Google? Andre Resende, a computer science undergraduate student at the University of Campinas in Brazil should know. When the company invited users to send in designs for its new favicon - the small icon that greets you when you access Google on your URL bar or your bookmarks list - Resende submitted one. His placement of a white 'g' on a color-blocked background was highly recognizable and attractive, so it inspired Google's new favicon. But that is only the tip of the iceberg as far as Google's interaction with its end user is concerned. One peek at Google Lab tells you how smart the company is with recognizing the users' pulse and resting its innovation on such simple needs. And what's more, users have a free hand in playing with the company's innovation while they are still in gestation. Here's is how Google has been changing the way we do things and building, bit-by-bit, the technology bellweather that tech buffs and geeks love to track and sometimes follow.
