An idea that's been floating around in my head for a few days has been the different types of "capital", particularly as they relate to gift economies. This is particularly interesting to me because open source communities and increasingly even modern development departments operate as gift economies.
Why is this important? Because it means you have resources your balance sheet doesn't reflect, resources that can be transformed into financial rewards or help you achieve goals that are orthogonal to normal business operations.
And that's all I'll say about that... for now.
