Several people have asked me how I constructed the visualizations that I used in my talk on del.icio.us. My own approach involved a fair amount of hand-rolled custom code - not fun for people unaccustomed to writing their own software and working from the command line. So as to give non-programming-savvy researchers a chance to explore del.icio.us - or other online systems with implicit network structures - for themselves, I have put together a short guide on using two Mac OS X applications, Anthracite and OmniGraffle, for this purpose.
Comments and suggestions are welcome.
I have added to the resources page a talk on del.icio.us, presented within the context of the Horizon Project VCOP. If you've heard about del.icio.us, but aren't quite sure what the fuss is all about, or if you've already tried it out, but would like to know how to get the most out of it, this talk is for you.
As always, I'm interested in any comments or feedback people might have.
