It's like Google doesn't even care how long or how much we've worked on our sites
They don't. They don't. They care about users and advertisers, they do not care one whit about webmasters or site owners. Individually we do not exist for Google. They're Godzilla, and we're the squashed villagers stuck between their toes. So if you want to know what to do now, the answer is capture your existing community and diversify your traffic sources.
