#2 is super important for folks who aren't used to working remotely to take to heart. It's really easy to feel the (self-imposed) pressure to be available all the time and feel anxious because you're not doing work for 8 hours straight -- that's the road to burnout. In reality most people only do a couple hours of "heads down" work on a normal day; removing the office politics and moving to a more asynchronous communication style simply makes obvious how little "work" actually gets done at most offices.
