I don't know about you, but it changed mine.

Google is basically my first destination when I have a question on anything -- whether it's looking for a restaurant, or solution to a bug I can't fix. I can't imagine my life without Google anymore.

Don't you remember the days without Google? I used to have 4-5 search engines open when I need to search for something -- Yahoo, Infoseek, Altavista, Meta Crawler, Excite... Thank goodness for Google I don't have to waste hours looking for something!

I use Google every day and so do millions (billions?) of people. It depends how you measure it, but Google has probably affected more people than Ebay.
