I just hooked up by blog (http) to Googles FeedBurner service (http -> pubsubhubbub) and in turn to a PubSubHubbub -> XMPP Gateway hosted on Google App Engine.
Why? To prove that you can get almost any web based content into an XMPP based platform like Cleartext ESM. I’ll post a screen shot of this post in ESM Desktop as soon as it shows up 
– UPDATE! That was quick – FeedBurner has grabbed the post and pushed it to the XMPP gateway, which in turn pushed it to my ESM stream….
Feedburner is really very useful for syndicating feeds from other websites.::~
i always use feedburner to syndicate my blog posts to other subscribers.-;.
