Too Long; Didn't Read
It takes too long to receive feedback, and it takes ages to get answers. Instead of having 1 email “in progress,” you might have 20, 30 or a whole lot more work in progress. The root cause is still there: it takes too much time to get feedback or answers. But what’s the alternative? We are all busy and we can’t just drop what we’re working on whenever someone demands our attention. We need tools (except for a basic to-do list) to manage all our tasks.
