"but I still find it interesting how difficult the search for an earth twin is proving to be."

Keep in mind that the only ways we have of detecting extra-solar planets is slanted towards high mass planets that orbit very close to their primary. Given that, we've found a lot of planets. So far, we have no method of detecting an Earth in a solar system like we have at any distance beyond the equivalent of our Oort Cloud. So unless we start picking up the equivalent of "I Love Lucy" on a radio telescope, we are blind to them...

Yeah, I know that Earth currently radiates RF so that it out shines the Sun. But with cable, satellite and point to point broadcasts, we radiate less and less every year. At some point our radiation won't be detectable any more. Chances are good that the same would be true of any technological society, there is only a century or two where high RF radiation levels are detectable...
