Yes, I think, there is life in the space around us. It will be just a question of time until we get in contact. And anyway if it is dangerous or if we benefit of the contacts with extraterrestial life - our timesharing here is just to shorten the date we find others.
I think: If you at Setiathome Project would be more on the mind of mankind, more users would participate. So why not writing more press articles? Spent space for advertisements in your website for bigger firms so that they have a reason to let their computer capability run with the setiathome client.
Why shouldn't I run this client? When systems are running, it's a nice idea to think that they do something ... :-)
I would like to start setiathome in multiple tasks.
