Came by this blog [ProgrammableWeb] recently which has a focus on web services and APIs. Or, in John's on words...

ProgrammableWeb is a web-as-platform reference site and blog delivering news, information and resources for developing applications using the Web 2.0 APIs.

It's part of the Web 2.0 Workgroup.

The Web 2.0 Workgroup is a network of premium weblogs that write content exclusively about the new generation of the Web. Combined, these sites reach a large readership of influential technology and media professionals.

ProgrammableWeb has a good listing of web-service APIs. Also a tag cloud if you favour the right side of your brain.

Passed by 1st dan test last weekend. Horay!!!
