What is the difference and how should they respond? It seems to be a rising frustration among power users that Google is increasingly becoming a wasteland populated by spam. For example, Marco Arment recently commented on his podcast how hard it was to find answers to simple questions on Google these days. He was saying that the content farms have basically created a page for every PHP function with thin content and rendered it useless. For a company whose goal is to index all human information it is a pretty big warning flag.
What is the appropriate user response? Go to Stack Overflow? Find a branded knowledge base like O'Reilly's Safari? I'm genuinely curious to know what we can do.
