Where should we point our radio telescopes?

• Targeted search of nearby stars:
  Aim at solar-type stars (of similar heavy atom composition) that should harbor reasonably sized habitable zones for planets. Currently studies are targeting stars closer than 200 light years away.
• All-sky survey:
  Some extraterrestrial civilizations may use high-powered transmissions, and these could be detected from the furthest portions of the Milky Way Galaxy.
