Earlier quoted context omitted.
I'm calling it as I've seen it from my experience. I think I made that pretty clear. I'm not trying to make a general case that there is some specific quality of non-profits that makes it impossible for them to be functional. As I said pretty clearly above, the wikimedia story sounds typical, based on my interactions with non-profits.
Your experience, though, does not meet the reality that there are many fine non-profit success stories. There are a lot of non-functional ones, but I think all folks are pointing out is that it isn't as dire as you have seen.
I wouldn't call any of the non-profits I've worked at failures.
Hell, many people have described companies like Microsoft as badly disfunctional, but it would be hard to argue that they are not successful.
If I stepped on anyone's toes with my post, I apologize. I was not trying to take a swipe at any one or any type of organization. I'm still involved with a number of organizations and admire and respect the work that they do.
