An aspect that I feel is often ignored, or at least forgotten, is the law of leaky abstraction. The whole point of visual programming seems to be to abstract more, but inevitably they always hit the exact same problem. The abstraction leaks, and now you have to implement an ugly hack. The only case I see for visual programming is as a standing for a DSL. If you have a very specific domain where you need a nontechnical person to be able to rewire some things often and autonomously, you might need visual programming (although you might be better off with a 50 line text file)
