Some results: - We have gotten a few replies from Santa Monica and Activision - By my count we have almost 400 tweets to Activision by now. - Links to the campaign are being thumbed up on youtube videos. - Lots of people are sending messages via PSN to inform other All-Stars players - The topic on the official forums is the highest kudoed topic - Some low level news sites have taken notice and might write something about it.
