There are excellent public interest grounds to have a search engine whose rankings are transparent.

I'd rather have a search engine or a compiler on a deserted island than a game.

Good SEO is the one that brings quality traffic to your site, not just to increase the traffic of your site.

There's nothing that cannot be found through some search engine or on the Internet somewhere.

Every major search engine has some form of paid placement.

Public interest is a very unruly horse.
