I feel the thing that many people are missing is that 10 minutes 'stand-up' meetings every morning are important because they encourage 'accidental communication'. You might be debugging something that just broke, and remember, 'Oh John said this morning that his main priority today was to add some code to XYZ, which affects this, so I'll just check with him'.

Contrary to popular opinion on HN, regular communication is important for most (if not all) business activities.
