Personal background
I'm a 32yr old missile systems engineer, and a keen amateur astronomer. When I'm not engineering missile systems, I can usually be found at the observing end of a telescope. I have two scopes, one 12" aperture telescope that is portable (well, kind of), and a fixed 10" telescope for CCD imaging of distant galaxies and nebulae. My ambition is to discover either an asteroid or a supernova. It's just a case of being in the right place at the right time, so watch this space... (literally)
Thoughts about SETI and SETI@home
Extraterrestrial life most certainly exists. We're just an insignificant little planet orbiting an insignificant little star. Just take a look up on a clear night - how many of those stars up there have insignificant little planets too, possibly teeming with life. For the diversity of life on earth - from microbes to sperm whales, I simply can't accept the unfortunately common theory that we are alone in space. Space is big, and to have only us in it would be an awful waste of all that area! We're still arguing about life on Mars, the next planet along, so how can we be so sure we don't have neighbours in a more distant part of the Milky Way?

Regarding beacons - look at it this way. Marconi first started sending radio signals back in the 1800's. In terms of the age of the universe, that is the tiniest blink of an eyelid. Perhaps intelligent extraterrestrials have since given up on radio (a few hundred million years ago?!) and are now using quantraspectroid coherent communication. What's that I hear you ask? Ask them! We haven't discovered it yet. I think the one thing that stands out (literally) is optical communication. Light is so vital to most living things. Optical SETI is well underway, and I think it needs to be given equal credence to radio SETI. Whatever we send needs to give our location - which is difficult. How do we know what co-ordinate systems extraterrestrials are using? Perhaps something pictorial. An arrow in relation to a view of the mily way, or known pictures of relatively nearby nebulae or galaxies. Narrow the search down a bit.

I run SETI at home because I believe there is something/someone out there. Crikey, I even upgraded my motherboard and CPU to run work units faster so I can get a bigger throughput in the time I am able to have my PC 'on'. To bring together all these PC's, and more importantly the believing users, for one cause is magnificent.

One day...
