review of Plinky will resonate with those of us who have nothing to say but, for various reasons, need something to say. "Plinky" to the rescue - "an automated version of the person at the party who takes an interest and asks you a question." Plinky says "We know you've got something interesting to say. Plinky is here to help you say it in a fun and compelling way." Pinky also helps you think of something to say by asking questions that might not have occurred to you, e.g. "Who would win a fight between a bear and a shark?"
