Not the same rubbish, different rubbish, many types of rubbish, but mostly rubbish. You have to work hard to find what you want. It is true in TV broadcast as well as in the Internet with search engines.
I know about a new startup here in Israel, that develop a kind of search engine per niche. Instead of using Google search, they research the niche with their experts and give you digested resultS per query - and it works.
