I belong to several of the Yahoo astronomy discussion groups and one of my favorites is the one on planetary nebulae. It can be dead quiet for six weeks and suddenly errupt into a passionate debate about whether post asymtotic giant branch stars actually overlap the proto planetary nebulae as a group. There is lots of heavy hitting technical jargon, my favorite phrase today is "axisymmetric superwind mass loss". If you can't get enough of geek jargon, try the Yahoo group discussions on astronomy.
