Google.com. I can only assume that if you haven't heard of it, you've been living in a hole for the past..20 years. Yup, Google's been around a while, and has made it's impact on society. I mean, how many times per day at work do you hear "Hey, where can I find.."Google it!"
The service Google offers is exemplary, and it's by far the best search engine out there.
Google also offers Google mail, Google earth, Google Adsense, and the forum Google Groups. All work well, and have virtually no bugs.
Not to mention the Google phone. (Google it? )
Amazingly, Google's first office wasn't a big building in silicon valley. Nope. It was a Garage. And from there, they grew into a multinational company, that is today the best.
If you need quality, speed, email, advertising, support, a forum, maps, a phone(!) then Google is the homepage for you.
