I am looking for a tool/script that will allow me to send out mass @mentions with a limited # of canned messages. Meaning, if a user wrote a message containing the text 'Toyota Camry', then I would write a message back with a specific @mention and a message about a Toyota Camry, but if he wrote about 'Toyota Prius' then it would allow me to write back with a different @mention and message.
At this point, I dont need much of a GUI or automation, it can all be script based where I put all the @mention users in a text/xml file, and the script could read from there and publish it using the twitter api. The goal is to test out the functionality and refine it before working on the GUI. That will be a later step.
