"Google has also created a new kind of work environment. It serves three free meals a day to its employees (known as Googlers) so that they can remain on-site and spend more time working. It provides them with free on-site medical and dental care and haircuts, as well as washers and dryers. It charters buses with wireless Web access between San Francisco and Silicon Valley so that employees can toil en route to the office. To encourage innovation, it gives employees one day a week -- known as 20 percent time -- to work on anything that interests them.
"To eliminate the distinction between work and play -- and keep the Googlers happily at the Googleplex -- they have volleyball, foosball, puzzles, games, rollerblading, colorful kitchens stocked with free drinks and snacks, bowls of M&Ms, lava lamps, vibrating massage chairs and a culture encouraging Googlers to bring their dogs to work. (No cats allowed.) The perks also include an on-site masseuse, and extravagant touch-pad-controlled toilets with six levels of heat for the seat and automated washing, drying and flushing without the need for toilet paper."
From the Washington Post profile this morning. The whole article is quite fascinating--and a bit scary. The thesis is essentially: "Google knows a lot more about you than you know about Google."
