I'm quitting SETI@home as soon as Classic dies. My reasons for this are that I have no longer have faith in the competence of the Seti team. The shoddy way that they set BOINC up making it live well before they had ironed out bugs (from what I've seen of the comments it's still bug ridden) and various other issues make me doubt the teams capability of producing good science. The cavalier way they dealt with concerns about stability and security shows that they have reached a point where they hold the users in contempt. After all if it wasn't for people donating compter time (and electricity, etc) they wouldn't have a project. I'm voting with my feet and putting my extra cycles onto another (non-BOINC) project.
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
