TRADE SECRETS: Pierre Abel, who runs French mom-and-pop app shop L'Escapadou, made Hacker New headlines back in 2011 with his post, “How I've Made $200k in the iOS Education Market." He's openly shared his sales numbers for 2012 and offers a host interesting tips for sales, getting feedback, networking, and other strategies that have clearly been working for him. One of his many insights: "A well orchestrated app release including blogs/promos/PR really makes a difference... but remember that it’s a lot of work, and the difficult part is also to stay visible when the promotion is finished."
