title: How do I discover RESTful Web services?
body: <p>When I want to find a "Big" Web service (WS-*/WSDL based) of required functionality I can simply google for ".... filetype:wsdl" because Google indexes also WSDL definitions. Or I can simply use some registries that already crawled the Web for WSDL definitions for me, e.g. SeekDa.com or ServiceFinder.</p>
  
  <p>When I want to find RESTful Web service (RESTful Web API) I may count only on the community, because it is not possible to distinguish between URI of RESTful Web service and other Web resources (e.g. Web sites URLs) and hence any focused crawler cannot tell for 100% sure: this is URI of RESTful Web service. So, I come e.g. to the ProgrammableWeb.com and I hope someone already used/found the service I'm looking for and registered it there.</p>
  
  <p>Recently, I was looking for the Web service for abbreviation expansion. I couldn't find it in portals like ProgrammableWeb, because no-one has put it there. Finally I was forced to browse through several abbreviation dictionaries sites, dig and drill there and I finally found Abbreviations.com Web service API in RESTful form. That took me a lot of time!</p>
  
  <p>Is there any other Way to discover RESTful Web services on the Web?</p>
