The Planet installation for the Linux.Conf.Au (the main Linux conference in Australia and one of the biggest and best Linux conferences in the world) is designed to only syndicate posts about the conference. I think that this is a bad idea, people who attend the conference actually see things and don’t have a great need to read blog posts about the conference. I believe that the benefit in having a Planet installation related to a conference is to allow delegates to easily read the blogs of other delegates. Then they can track down the bloggers if they want to discuss the blogs, or add them to their favourite feed reader so continue reading after the conference.
So I created my own Planet for it . I started the installation with a feed from the official Planet LCA 2008 , then added the full feeds for people who appear to only have a partial feed aggregated on the official Planet. I also added Bruce Schneier’s Cryptogram  blog (Bruce is the opening keynote speaker for the conference).
If you have a partial feed of your blog syndicated on Planet LCA 2008 then please let me know so I can syndicate your blog’s full feed.
