This is really cool. The BBC NEWS wikiproxy runs the BBC through a filter that linkifies the text to hit Wikipedia articles, and adds in which blogs are pointing to the article. How cool is that?
Of course, there is the second-order problem: will (would) blogs start linking through the filter itsef and thereby mess things up?
At any rate, not only is this cool in practice, it’s cool in theory. Wonder what is going to happen to all those “Place” names Word keeps underlining? One of my grad students uses a plug-in that lets her get instant translations of words from English to Chinese, and record them for later. Lot’s of people are using the web to help them improve their reading skills in second (and third, etc.) languages. This is how people will learn in the future. (Sorry, lost who I found this through…)
