It looks like the “Send Pings” client in Typo only supports the XML-RPC
implementation. The weblogs.com spec for the ping API
(http://www.weblogs.com/api.html) also has a REST implementation.
XML-RPC is certainly the more robust of the two, but the REST option is
used (even exclusively) by a lot of sites. Any idea how hard it would
be to implement a REST ping client?
