More useful, I think, is to browse the network of del.icio.us users as defined by their inbox subscription lists (as suggested by Paolo Massa):
Comments
All fields are optional, email address will not be shown; no HTML, URLs are automatically hyperlinked.
It is amazing how fast you are in making reality out of an idea!
As a suggestion, if you want to display just the social network you might want to strip off some subscriptions. For example, my subscription export (visible at http://del.icio.us/inbox/phauly) is
- */trashware #pages tagged by everyone as trashware
- cshirky #pages tagged by cshirky
- ethanz
- joi_ito
- zephoria/academia #pages tagged by zephoria as academia
Based on this, we can say that my outgoing social edges are {cshirky, ethanz, joi_ito, zephoria}. So the idea is to remove subscription that start with "*/" and to extract the substring until the first "/"
I'm sure you are going to write it in perl in less than 20 characters!!! and less than 12 seconds ;-)))
The second part it already does (stripping anything after the slash) - your last subscription hasn't showed up yet because (I think) you just added it and I'm caching the pages for 24hr.
The first part (asterisks) I left in on purpose, just because it's interesting to see when people subscribe to the same general purpose tag as well (so yes, it's not just a social network).
