PHBs need to assert their control. If you are not there then they feel somewhat lost. Believe it or not, their bragging amongst other managers is firstly about how many direct reports they have.

If you get a bunch extroverts onto a team, they want to have meetings, pizza lunches, etc. All that activity makes them feel productive.

On the other hand, if you have introverts working remotely they can get on with the task at hand. Bring them together once a month for a day and it will form the social bonds that work well when they're back to interacting over the internet - the exact tools is a question of preferences.
