I’ve set this site up as an RSS feed for those who are interested in that sort of thing. You can find out more about it at RSS — A Primer for Publishers and Content Providers.
In short, it allows web browsers and web sites to display an up-to-date summary glimpse of the content of a site like The Picket Line without having to visit the actual site to do so.
If you think an RSS feed of The Picket Line would be useful for you, you can pick it up at http://www.sniggle.net/Experiment/rss.php. (Don’t expect this link to look good in your web browser.)
Update: there’s also an RSS 1.0 feed available now at http://www.sniggle.net/Experiment/rss1.php that includes both summaries and complete entries.
