@cdevroe i think as soon as the Instagram founders left, because they couldn't stand Zuckerberg anymore, there was nothing to stop Zuckerberg from changing Instagram to fit his needs. I remember reading an article in the past that part of the deal with Instagram was that they were going to be left to their own devices. As Instagram slowly became more popular than FB, Zuckerberg was annoyed and wanted to reign in Instagram. Soon enough the founders left and Instagram came fully under Facebook's control.
I use Instagram as a curated feed for cars. I still have not found any site, other than Speedhunters, that delivers amazing car culture/motorsport photos. I haven't posted to Instagram in awhile now though.
I think you’re right. The founders of Instagram leaving the company was definitely the death knell for me too. Kevin and Mike were excellent product people. The current batch of people, and their incentives, aren’t aligned with what I want from a photo sharing app. That being said, they are very likely very good at their jobs.
