While we’re on the subject of the web that is Wikipedia, four-man, Baltimore-based development shop Friends of the Web made Wikiweb, an iPad app to research and casually browse Wikipedia. As you search for a topic, an interactive network that shows connected articles appears on the left alongside the current article on the right.
Wikweb: Now even easier to find yourself lost in Joe Pesci trivia.
A worthless app: you already know which articles are linked; they are hyperlinked! All this does is use half your screen on an unwieldy graph.
