But after reading it, here is what I really want to know: what does "a few tweets" mean? I know many people (myself included) who have tried to "kick out a few tweets" and did not get 1000 email signups quickly. My belief is you are writing it because it makes a better story, and puts emphasis on your design. But is it true?
How did the tweets get out to that many people in your target audience? Do you have many followers? Did an influential person retweet it? If so, was it a friend or an unplanned retweet? I'd love to hear more about this side of the story.
