The Site Analysis report used to have a terrible reputation, but I found it very useful and I'm still sad that we don't have a replacement.
In particular, I used to love using it to find out how people flowed between two points on a site - it was really useful for properly answering the "can you tell me the top ten journeys?" question that always gets asked!
I've tried to get Adobe interested in a new workspace visualisation but they haven't bitten yet
(all votes welcome!)
Anyone else still lamenting the passing of the old Site Analysis report?!
