I was at one of the first "DevOps Days" conferences in Hamburg where we sat in a huge circle and everyone had to introduce themselves and say what they are "passionate" about. Although I am a little bit more interested in the craft than an average 9to5 programmer I couldn't bring myself to use that phrase and could only articulate what I am "interested in". I am not a native English speaker so maybe my feelings around the meaning of "passion" are distorted but I didn't get how you could be passionate about continuous integration.
