ive been suggesting this to my teammates for awhile. i use mine to track long term goals, walk myself through my status on my in progress work items to prep for standup, and take any quick notes when i learn something new or need to remember something like a due date or a point of contact for something. pretty cool looking back through my old ones as well since I've been doing it since I was an intern (ive got like 5 years of notebooks now XD)
there is no reality where the chinese government doesn't have whatever access it wants to this data. lets be real here people. thats just how they roll
