Article on one of the negatives for site owners and the web as a whole in the emerging popularity of RSS. As RSS feeds can be requested automatically at set intervals by newsreaders this can lead to a large escalation in bandwidth usage for a site. There are aspects of the protocol which, if followed by newsreaders, minimise the load on servers. These measures are not implemented in every news reader. The other alternative discussed is to minimise the amount of information sent in the RSS feed. That is, just sending the headlines or first sentence without sending all content.
A good analysis of the limitations of RSS. Some limitations involving convenience and usability (e.g. no reader packaged with MS Windows yet), others issues for the site offering rss feeds (e.g. bandwidth issues with repeated downloading of full feeds), and some related to issues with the format itself (e.g rss does not allow secure access necessary for paid content delivery).
On the subject of RSS, the site I recently launched, What is RSS? RSS Explained, has been receiving a steady flow of initial traffic. Google had it in its index within a couple of days of putting it up and there are a few sites linking to it already. People seem to be finding it a useful tool to explain RSS.
