I also use Google, for two reasons:
1) There's nothing more generic in Internet-purpose than a search engine ... if you're bothering to open your browser at all, there's a good chance, at least a little better than anything else, that it's to "look something up." Statistically speaking, if there's got to be a default, it's the best choice (for me).
2) The page is very simple, and minimalist ... fast to load.
