The idea is, using twitter API we will be listening to tweets to a twitter address, that tweet is automatically fetched using a listener agent (we can use java here)
The db will return back the possible response with options available for user to reply.
The user has to chose a response and reply to the tweet, and we can fetch the in reply to information encoded in the tweet to mark it with previous tweet.
The system will be as marvelous as annoying to the user and it will be fun to screw someone out. Right?
How does it sound? Already have dibs on this wait and watch....
