I was reading an article over on the New York Times website and accidentally stumbled on one of the coolest features I’ve seen on a website. In the body of the article, you can double-click on any word and a definition will pop up–anything from “science” to “Web 2.0″ to “bubble.” This is the kind of feature that really isn’t necessary for all sites… or even most sites. But for something like the New York Times, which probably has a pretty decent foreign readership–or really any “information source,” I just think it’s a fantastic idea.
