 Yes, effectively. (Opennet behaves a little differently -- your
 neighbouring peers are constantly being swapped and optimized to
 approach a small-world topology.)
Does this mean that in Darknet mode the peers are not swapped?


 The main advantage, I believe, is security -- opennet nodes are
 relatively easy to monitor and traffic-analyze, given a strong opponent
 like Big Brother, by compromising your (constantly changing) opennet
 peers. 
OK, I can see how the constant swapping may give a malicious member 
the opportunity to build a topology of the network that would lead to 
IP addresses of nodes owned by real people.  Correct?
Given that this would take quite a bit of effort and time, 
is there the possibility of putting in the network some decoy nodes
(honey-pots) that could lead to the violators?

 In darknet, they would have to physically compromise each of your
 friends. Also, since opennet nodes are ... open ... all opennet node ip
 addresses can in theory be listed, and blacklisted. To do this in
 Darknet would require physically traversing the entire network.
Is it because of differences in routing algorithms?
If I had a P2P with only 3 nodes that I own, then I would not have any 
exposures.
If I have a darknet, is it through some trust that security can be achieved?
What makes darknet so much more secure than opennet?


 Darknet was implemented to fix the rather serious security issue of
 opennets. 
Which was?

Correct. They're fixed. They are your trusted friends.

There is that, but they can also in theory replace all of your peers,
and thus know what keys you are downloading/uploading.

Sure, if you don't mind having your node seized :b.

Yes -- you actually (hopefully) know and trust each of your peers,
unlike opennet strangers. I believe that is the only significant
difference. (To infiltrate a/the darknet, physical surveillance /
kidnapping / bribing / torture is necessary.)
