Another variation on my twitter airport game.
Here is another game.. This one requires a traveling companion who is in on the game.
When you are an airport, search for other twitter users at the same airport. Look at their tweet stream and try to ascertain where they are going. Find the appropriate gate and look for them. Once you find them Sit next to them, and watch their twitter stream on your cell phone..
Converse with your traveling companion. Whenever your target sends a tweet, try to change the topic to match their tweet. Keep doing this and see if they ever catch on or join in the conversation. If they do, try to let the conversation die until they tweet again... then repeat the process... As their flight is leaving, send them an @reply thanking them for the conversation.
