1. Usually you need to look through multiple posts to find your answer. It&#x27;s still quick, but remembering you wrote up about it before and searching for it and seeing your more precise note about it is faster.<p>2. I&#x27;ve been using mine to also keep track of tools I encounter but don&#x27;t have time to investigate, or for hotkeys or features in specific applications that I didn&#x27;t realize were there before. I just took a quick glance at my old notes and was reminded about a feature in XCode that I had completely forgotten about since I wrote the note.<p>3. It&#x27;s great for a refresher before diving back into a language you&#x27;ve had on the backburner for awhile, and&#x2F;or before going in for interviews where you know you&#x27;re going to be quizzed on random knowledge from past languages you&#x27;ve used before but maybe not recently.
