After reading this article by Ben Hammersley, it stuck me that what the weblog community needs is a Weblog API Multiplexer service. This would be a service that would accept a ping containing some posting info, e.g. the entry's trackback snippet and then make all the various weblogs.com, blo.gs etc pings for you, thereby reducing server load for thw weblog author. To make it a completely hands-off operation API developers should be able to register their APIs with the multiplexer, specifying what information they require, and get added to the ping list automatically.
