Good question, I'd have to say the pay off per effort simply was not there for them. It didn't help that they had the option of simply dictating the work back to us lower status grad students.

So one might say the issues were more largely organizational. But these weren't lazy people, they were always looking at new tools and techniques. And they were struggling to get any payoff with the tools we had. Sadly the focus of the project was not visual programming, so we were not focusing on the users issues.
