<?xml version="1.0" encoding="UTF-8"?><item><title>"Every apparently non-polling technology is built on polling"?</title><description>&lt;div&gt;&lt;a href="http://www.scripting.com"&gt;Dave Winer&lt;/a&gt; is wrong on this one.  He's saying there's no way to do what RSS is doing without polling.&lt;/div&gt;&#13;
&lt;div&gt; &lt;/div&gt;&#13;
&lt;div&gt;RSS is based on an aggregator connecting to every server that the reader is subscribed to every half hour or so and getting a fresh copy of the RSS feed.  This is wasteful, and it forces the publisher of the content to pay for the bandwith required for people to read it.&lt;/div&gt;&#13;
&lt;div&gt; &lt;/div&gt;&#13;
&lt;div&gt;Usenet is a different model, but at a lower level (where it's all about the invidual articles posted), it's doing something very similar to what RSS is doing:  Letting a user post something, and letting millions of other users read it.  And it's doing it without polling, and without putting any burden on the person writing the material.&lt;/div&gt;&#13;
&lt;div&gt; &lt;/div&gt;&#13;
&lt;div&gt;Usenet would be an excellent model for making RSS scaleable.  But hey, NNTP isn't XML-RPC so it's not cool.&lt;/div&gt;&#13;
&lt;div&gt; &lt;/div&gt;&#13;
&lt;div&gt;Jabber would be another model that would work BTW - a publisher posts a new article and then sends a message, which gets propagated by a network of connected servers to anyone that's interested.  No polling involved at all.&lt;/div&gt;&#13;
