Instagram succeeded for many good reasons, including its design, its viral qualities, its simplicity, and the fact that its engineers focused so obsessively on making sure that it works all the time. Part of its success, no doubt, is the fact that it was just in the right place, at the right time, with the right, crowd-pleasing mix of features.

I think it’s important to publish what you learn. There’s really no school for front-end development. You can’t go to a university for a JavaScript degree or a class about how browsers work. Most of us learn from blogs and Twitter. Early in my career, I learned a bunch of things whenever I worked on a project, but I never told other people about them. So my general advice is to publish what you learn, share with the community, and collaborate on projects that help move the community forward.
