Burnout in the FOSS community is real, and I'm glad that it's something that is being talked about more in blogs and conferences. There is a different flavor of burnout and emotional toll when you are sacrificing for a cause you believe in (especially in FOSS where people are often working for free or at below market rate). Working for a cause you believe in brings the highest highs when things are going well, but the lowest lows when they go badly.
