Ben Orenstein is joined this week by Daniel Jalkut, the developer of MarsEdit and other fine software. Ben and Daniel discuss the origin of Daniel's twitter username, his history at Apple and his work there, and how it influences what he builds today. They also discuss the challenges of running your own company, and how Daniel's priorities and rule systems help him get things done, how the success of MarsEdit takes up his attention at the exclusion of other ideas, and how he thinks about failure. Then then go on to talk about App Store versus direct sales, why Daniel still sells his software outside the app store as well as in it, and what the breakdown of sales are like there, as well as Daniel's thoughts on App Store pricing and the benefits of being in the app store. Finally, Daniel tells us why he thinks git is like a PC and Mercurial is like a Mac, why he dislikes git, what he thinks makes a good podcast, how his podcast has changed, and much more.
