The content restrictions seem overly restrictive.
Won't work: How should a demolitions expert expect to be treated by an architect? Works: How should a saint expect to be treated by an architect? (silly questions I know, just to make the point)
If I want to mind-map political joke ideas or brainstorm adult toy names that's my business.
I can't even use this tool to brainstorm about the pros and cons of different content restriction systems, the irony.
