Planet Apache is provided to aggregate personal blogs from Apache committers. Apache also hosts official project blogs for those top level projects or incubator podlings that request them.
Apache Committer Personal blogs
Committers with personal blogs are encouraged to add their feed to planet.apache.org for aggregation. To get your personal blog listed and aggregated, check out the planet module from our SVN repo and edit the config.ini. See the README and FAQ files for details.
$ svn co https://svn.apache.org/repos/asf/planet/
