I do like Sozi ;-)
At first I found it hard to understand but now I get deeper and deeper.
My site serves me as public memory and I hope I can increase the popularity of sozi.
You are right, there is no need for the path to contain more than one segment.
In the meantime I have corrected my site and completed the example.
I think the path needs to alter the direction in order to take effekt.
A linear path with one segment seems not to effect anything.
