This is a great question, and I think the trouble here is that there is a temptation to answer with one off anecdotes from the idiosyncratic example of a single use case. The more peculiar, individualized, unique, and unrepresentative, the more likely it is that we're going to hear that. This temptation is very strong on HN. I honestly would be fascinated by a blog that gathered together all the extremely specialized use cases that people use as examples of why product XYZ wasn't good enough. That way of thinking leads to interesting to discussion but needs to be tempered by stepping back and looking at how representative those examples are, and I think that step is the point in the process where these conversations always break down.
