When I look at the top team in Boinc, it is SETI. I can't believe people are donating so much resources to looking for Aliens, then to medicine and physics and many other much more relevant projects to the well being of the human race. I still like SETI and have it added to my Boinc projects, but I think people are going overboard with it.
The 500mm milestone = est. $300,000 in compute resources donated to scientific research!
