This situation has changed and I will give you three reasons to use/adopt FuseSource documentation for your Apache Camel, Apache ServiceMix and Apache Karaf projects.
Reason 1 : Fuse maintains history of Apache releasesApache websites uses Atlassian Confluence to maintain content publishes for each Apache project. This tool does not allow to create a history of the different releases of Camel by example (2.6, 2.7, 2.8). This is not the case with FuseSource documentation which allow you to browse a specific version like the current. And with the help of google, you can make specific search like that
site:fusesource.com/docs/router/2.8/ "followed by the keywords"
site:fusesource.com/docs/router "followed by the keywords"
Reason 2 : Javadoc and Schema are well documented
Javadoc like XML Schema are also 2 interesting examples as there is no XML Schema javadoc on Apache websites for by example Spring DSL language. This is completely different on FuseSource web site as you can read the documentation and discover what are the tags or attributes to be used for specific Apache Camel DSL words. Here is an example containing the options proposed for Apache Camel Dataformat. http://fusesource.com/docs/router/2.8/xmlref/http.camel.apache.org.2033734988/element/dataformats.html
