This is because right now, there just aren’t many well-known RESTful services that work like the Web. In previous chapters I wanted to show you clients for real services you might have heard of, so I had to take what I could get.
The del.icio.us and Flickr APIs are good examples of hybrid services. They work like the Web when you’re fetching data, but they’re RPC-style services when it comes time to modify the data. The various Yahoo! search services are very RESTful, but they’re so simple that they don’t make good examples. The Amazon E-Commerce Service (seen in Example 1-2) is also quite simple, and defects to the RPC style on a few obscure but important points.

I can’t use Flickr or the del.icio.us API as examples of how to design RESTful web services, though. That’s why I covered them early in the book, when the only thing I was trying to show was what’s on the programmable web and how to write HTTP clients.
