I'm a big fan of Seti@home ( http://setiathome.ssl.berkeley.edu/ ) and was wondering if I created a Seti TechTalk group, if anyone would be willing to join it. ;)
For those who aren't aware, Seti uses our unused CPU time to investigate satellite reads in search for extraterrestrial intelligence. ;) It's funded by The Planetary Society, Sun, Intel, and many other big companies, and has been around for many, many years.
