blo.gs cloud interface

blo.gs has a great href="http://blo.gs/cloud.php">cloud Interface that performs roughly
the same functionality I was href="http://revjim.net/archives/2003/04/30/9497.php">speaking about
yesterday. The only problem with their interface is that it only
sends pings that were made to blo.gs, and not any of those that were
imported from weblogs.com. Additionally, it will only send you
notifications for EVERYTHING as opposed to allow you to request
notification for only one or two blogs. With proper cloud notation in an
RSS feed, and the ability to subscribe to a feed via XML-RPC, this could
really work well. I wonder what blo.gs's plans are for the future?
