WebApps and Meta.WebApps are listed, as WebApps has entered the private beta phase.
Note that the
state property for those two are
linked_meta respectively, values nobody has presumably seen before (except in the docs).
linked_meta site is implicitly in the same state as its parent site.
Also note that the
name for both are temporary, assuming WebApps graduates to a full site. When/If such a graduation occurs, webapps.stackexchange.com will be moved to the
aliases array (which has been documented for awhile, but has not been in use).
If you are caching objects with respect to their site, be sure to check
aliases in addition to
site_url when doing a lookup.
