How do you attract developers to the world's first grocery API? How about by promising it won't go away any time soon? That's what Tesco's Nick Lansley has done in his recap of their first developer conference.
When Zappos released its API, there was a strange restriction: no mobile applications. While sometimes lawyers write terms that aren't formally enforced, Zappos made it clear on its API mailing list that it was serious. Soon, the restriction will be removed and mobile applications will be allowed without written approval.
