A toy for your amusement...
To keep you occupied today, I thought I'd share a neat little toy with all of you. It's called Amaznode and it is a way to produce a network graph of products on the Amazon.com "People who bought this, also liked this" list. You just throw in a search term, like an author, and watch the tool dig away.
To give an example, let's try a search for everyone's favorite blogger: Jeremy Freese. We enter his name and execute our search, and eventually get the following image:
If you mouse over any of the book covers in the network, you get a title. And, as you can see, there's Jeremy's magnum opus:
If you want to see a really interesting network graph, try a search for Playboy or Harrison C. White.* A neat little diversion, and a useful way to maybe learn a few things.
* Which you choose depends primarily on exactly how juvenile you are.
