I agree with this, but there's a pitfall. Lets say you want to get conversation done at either the start/end of day or both. This is efficient because then you can work interrupted throughout the day. However, when you're not available to answer every ping right away or your "online" status isn't green, then it puts you in a bad light because the managers think you aren't working and/or don't care/aren't a team player.
