Woody Zuill discovered the technique with his team — and has been writing about it on mobprogramming.org for for a while. Woody kindly agreed to join us remotely via Skype (sorry — no recording!).
You can watch Woody talk on mobbing from Øredev 2013:

Woody summarised mobbing as:
All the brilliant peopleSome of the points we discussed were:
Working on the same problem
At the same time
On the same computer
- How mobbing helped alignment within the team
- How it removed the necessity of some "standard" practices (e.g. you don't need stand ups because everybody already knows what everybody else was doing)
- How mobbing helped foster a sense of safety since everybody was always aware of how decisions came about.
Give the talk a watch — it's worth your time.
