Hi, This is just an idea... In the open source software world, alot of projects have "planets" which aggregates blog posts. I'm sure alot of dz.com users write about skydiving in their blogs. livejournal, wordpress, blogspot, etc. So it would be interesting to aggregate them here.
For examples see: http://planet.gnome.org/ http://planet.debian.net/
And the software that runs this: http://www.planetplanet.org/
