Smart-alec knowitall

The Googlers strive constantly to capture all knowledge and fling it back at us in their search results. Last month it started to track movie quotes and seek to link the results to film reviews and other filmic resources. Example: One ring to rule them all. The trick is to preface your query with "movie:". Works too.

Last week, Google added satellite imagery to its tasty maps and today the search engine colonised another territory: encyclopaedias. If you're looking for general facts (say, capital of Ireland), Google's best guess appears up top, linking to a reliable source online.

Funnily, hunting for the best search engine suggests rival Dogpile. How scrupulous.
