This is a very good way of describing the problem. Journalists are humans that search out salient news and stories and work on bringing it before the public. There (should be) professional ethics in their work that inform these choices. Google, meanwhile, just throws up whatever it finds. It's doubtful a journalist would ever take interest in the odd smattering of risqué/questionable moments of your neighbor, but Google's more than happy to serve them all up at your request.
