Daniel and Manton catch up on MarsEdit 4's progress a week after releasing. They talk about the anxiety and fear of making a huge mistake when releasing, and the relief of discovering you haven't. They reflect on the effectiveness of direct email to inform existing customers of updates, and how the quality of a mailing list deteriorates over time. Finally, Manton looks forward to releasing Micro.blog to the public, and Daniel encourages him to generate more PR fanfare around that.
