> Google already does this, by its measure of "useful" (to you).

The point was that they've been successfully more aggressively penalized, to the point where many of these sites are now no longer showing up more.

> If you don't like it, you can search those sites directly. For example search for "ehow:how to ask a girl out" was that so hard?

That defeats the primary purpose of using a general search engine - namely to get ranked results across a large number of sites.

But it is still doing its purpose. You can just tell it what you want to see.

I wish there was a way in Google to indicate you'd like to see results from a site ranked higher FOR YOU. I imagine they already learn that when you click on that domain in two separate searches.
