It’s sometimes good to remember that software is developed by people. Those people have lives, partners, children, problems of their own. They’re fallible, and the development cycle is in itself unpredictable, full of pitfalls even for the most experienced. So when your favourite new thing isn’t released on time, try to be a little understanding.
