Simon has just checked in support for content negotiation for Aggie. Hopefully well see more tools support this. RESTLog has always supported content negotiaion. For example, if you do a GET on the url http://wellformedweb.org/news in a browser you will get the HTML version but an RSS aggregator that supports content negotiation will get the RSS feed from the same URL. Now there are few aggregators that currently support conneg so RESTLog allows you to add a query parameter to over-ride the content type. Thus the other way to get the RSS feed is by the url http://wellformedweb.org/news?rss
