For those that haven't heard or don't remember, DEVLOOP stands for Developing Excellence Via Leveraging Object Oriented Principles. It's basically an internal user group started by Paul Clements and myself back around late 2006 or early '07 (I believe Jay Smith was heavily involved early on too). The acronym was coined by Paul himself if memory serves. Since we're OOP and pattern zealots, the name fit perfect!
For me personally, devloop has been invaluable in my career and I can't think of a single thing that has done more for me.
