As we keep releasing webservices that fall into brand new categories, such as the Content Analysis service or the My Web service, we realize that there isn't a mailing list that everyone can use to discuss these services. Rather than create a new list every time we create a new service category, we've created a more generic list: yws-search-general. Any webservice that isn't covered by the other lists should be discussed there, as well as any general questions about the webservices.
We'll still create lists for major new services as they come down the pike, but this will ensure that you have a place to discuss any of the services without being off-topic. And it means that you don't have to keep up with lots of mailing lists as we launch more new categories. Or perhaps I've said too much...
