Twitter’s updated Mac app wasn’t made by Twitter
The irony here is profound.
This should be a case study in modern business school.
They killed a vibrant ecosystem investing blood sweat and tears into beautiful apps for various niche and mainstream audiences ostensibly to control the experience (actually to control the eyeballs) and then ultimately outsource building the experience.
The result is a shitty app shipping years late.
Lesson: Developers rule. In today's API and software economy you must empower them and get out of the way.
