Imagine government and other web sites answering an open ended collection of English questions, and also explaining the answers in English. Imagine people socially networking, Wikipedia-style, to continually expand the range of questions that can be answered.
The approach starts from the observation that data by itself is necessary, but not enough, for many practical uses of an intranet or the Web.
What's also needed is knowledge about how to use the data to answer an ever increasing number of questions -- such as, "How much could the US save through energy independence?" , "Does a high level of national debt stifle economic growth?"
There is technology online that can leverage social networking for the significant task of acquiring and curating the necessary knowledge -- in the form of Executable English.
