As an Indian growing up in the 90's, I went thru' the perhaps unique situation during the growth of the Web, where hyperlinks were targeted for breadth but the existing connection speed enforced the decision on you whether you'd stay with the article (ie: depth) versus whether you'd explore (ie: breadth). Honestly, it was a pretty hard decision and while I think this is a good effort to question something fundamental to the Web and how we interact with it, I'm not sure this well intentioned proposal would really work in the absence of a physical limitation by bandwidth.
