Now with links!

Some of my favorites, over on the left below my beautiful portrait. This presentation by Mark Bernstein (or read the paper) discusses his simulations of the concentration of traffic on the web under different assumptions about linking. The take-away for me was that including links to a variety of web sites (a blogroll) creates a positive externality that helps preserve what Bernstein calls the "long tail" of diverse and potentially important but infrequently visited web sites. That kind of web "biodiversity" is worth preserving. Of course, the links can only do any good if someone gets to them in the first place... dear reader...
