Because it's about the journey and not just the artefact. If you're not thinking of something that's useful and preparing snippets to share every day you are not practising it. Having to come up with something stretches your imagination and critical thinking skills. What's true for the writer is true for the reader - if you just shared a simple repository with tricks, exceedingly few are going to read that, and the ones who do will forget it. Daily practise is important.
