Definitely. I'll fire you an email =)... I basically want to get an understanding of what pitfalls and issues that you had exposure to.

Fundamentally however the reason I keep thinking about that graph is that I keep wanting it. I wander into a complex nested discussion online which seems interesting and just want to see it visualised. Select statements and see who's making them. Focus on a part of the discussion one step at a time. Find commonalities and differences marked up.

EDIT: I sent that email I mentioned, not sure if you've seen it =)...
