I know that sometimes some technical people use the phrase "Web service" to refer to a particular method of building web applications, using WSDL, SOAP, etc., as standardized by W3C. Personally, I find this a confusing use of language, as many ordinary users understand the phrase "web service" to refer to a web site or web application that provides something useful to them.
Anyway, looking through the questions currently tagged with the web-service, the usage seems to be all over the place. I don't see any evidence that it is being reserved for W3C-style "Web services" technology (with WSDL and all that other gunk). Instead, it seems to be used in the sense that ordinary users would expect -- effectively, as just a synonym for "web application".
Should we make web-service a synonym of web-application, and phase out the use of web-service? (If really necessary to have a tag for WSDL-style stuff, we could plausibly introduce a tag like wsdl). What do you think?
