You have probably used the Google search box a thousand times, but did you know you can use it as a calculator, currency converter and conversion tool for imperial-metric measurements?

Eg. Cut and paste this to the search box $500 USD in AUD or 150 calories in kilojoules, or 15 feet in meters

There is a lot of buzz around Wolfram – a semantic search engine. That is search engine you can ask a plain language question of and it gets what you mean. This site is in beta, and frankly doesn’t have enough data yet to be useful.

Ask , formerly AskJeeves was also suppose to work like this – ask a plain language question and get the answer. Ask can be quite good, but no where near this information nirvana.
