Hey, I come here to offer useless kvetching and complaints, not solutions :). Seriously, if I knew how to solve it, I'd be the CTO of Google. But I'll make a couple of guesses. I think they need to go for a lot more human input. It goes against the grain of everything they do, they want to solve everything algorithmically. But SEO is just too good at abusing algorithms. I think they need to get more humans involved,…
> That's a lot harder for most people to manage than just using a search box. Hey, sounds like a business opportunity. "Join our bogon-buster network! [fine print: invite only, your activities and reviews will be rated by other members.]" Of course, after awhile, you'll need another layer on top of it to make sure that your bogon-buster networks aren't full of spammers themselves.
I actually think a similar problem has been partially solved by Twitter already. Twitter grows but the content curation is done by the people you follow therefore new users don't affect your interactions on the site unless you let them. Of course, there's gardening work which has to be done by the user in getting to this point but it would probably be less work than browsing some of Google's search results.
Additionally the intelligent thing would be to mine the social interactions of authoritative users to provide public data for users that don't want to engage with the app.
edit: Of course, it's possible to become an authoritative spammer in which case as a power user you will still need to garden the group of users that you interact with.
