Nice article about the need to spend some SETI time looking for AI signals and hang-outs, rather than focussing solely on the activities and locations of biological life-forms. Personally I still think that "first contact" is likely to be with a dormant/dead AI controlled Von Neuman type probe in orbit around a gas giant or a NEAR type orbit.
