I disagree. But that's only because I'm interpreting the hierarchy differently. If I am in the computer context, I expect to see everything related to computer work. The child node, online, is a subset, a special situation to the computer context. If I look at actions for online, I want to see only online tasks that are a subset of computer tasks.

I think that my take on this comes from being a computer scientist and mathematician, where subnodes are subsets.
