I run Seti@home because I think it is important to support a project which might be important for all of us. Perhaps one day mankind will discover something which would change the situation for all of us. And I have the dream.
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.
