I have been using Yahoo for a long time now I can't say enough about Yahoo. I keep coming back to Yahoo. I get more accurate results, and less annoying top of the page promotional websites. The site is fast and responsive.
Why is Yahoo better than google? Well, in short, it's not.
Google is by far my favourite search engine, but in terms of homepage, it has nothing on Yahoo!
Yahoo provides you with the top stories of the day as well as other topical things that might take your fancy if you are simply bored and have nothing else to do.
Google offers a search engine but if you sat looking at the google homepage for a few mins you can safely assume you are day dreaming or slightly deranged. The same cannot be said about yahoo!'s homepage.
