I have a rule that I only collect data: - if it is immediately and directly useful to my primary goals (the goals come before the data), and, - if I'm confident in advance that the results will have some statistical power (so, A/B testing colour schemes is out), and, - if I have planned in advance what the business consequence of the data analysis is. Having any more numbers than that just creates obsession. Aren't we all posting comments here, looking for validation from the upvote counter?
