Agree and I think there's a a few big opportunities. e.g. a better job search engine. Search in some form is what most of us spend a huge amount of time doing every day. Even searching within web pages for the relevant content we're looking for. Also Google are barely keeping their head above the web spam and filtering out spam is a very hard problem which may be better solved with a blend of human intelligence. Before you disagree with me consider that there are vast farms of humans creating SEO content and the content-gen business is growing extremely fast.It's the thing that scares Google the most in search.
