So I guess that many people here agree that perhaps the user interface is the most important factor when choosing a search engine and not as much the kind of results it returns.
Not necessarily. If I didn't get good results out of GOogle, I woundn't use it. Yesterday, I did a search on Yahoo and Google-- the Yahoo results filled a page, the Google, many pages. I didn't emphasize that factor enough when posting the first time around.
It is incrediably nice that Google is simple and elegant.
