With a billion searches a day, I won't claim that we'll get every query right. But just because we don't "solve" one query to your satisfaction doesn't mean we're not working really hard on the problem. It's not an easy problem. :)

There's a growing concern/consensus that in loads of non-spammy niches, the only way to get decent rankings is to build links.
I know this is naturally something that would be very hard for Google to tackle (since if 'junk' backlinks = domain penalty, black hatters would simply spam their competitors' sites with backlinks and get their competitors deindexed), but are there active efforts being made so that gray and black hat link building campaigns aren't (in some cases) pretty essential to a site getting good rankings?
The simplest response is that link spam works, has worked for years, and coming into 2011, it appears to be as strong as ever in terms of ranking sites for competitive niches.
