What surprises me is that after all the years of space exploration, sending up telescopes, probes with messages on them and boincing out radio waves, it's only now that someone's come up with the bright idea to see if anyone else is doing it!!

Also, why only look for earth type signals? What makes anyone think that signals being sent out are Earth type anyway??

Sorry in a grumpy mood today!!

Main problem has been radio interference from THIS planet, it drowns out much of the subtler signals from outside our own system.
As far as the type of signal, it's a safe assumption that the elecromagnetic spectrum is the same most anywhere, and if any intelligence out there were using the bands that support communication, we might be able to detect it.
I haven't run it in a long time, but I used to have the SETI screensaver on my computer- it's a shared processing effort you can join in on, looking for coherent artifical signals...
