 browser-45-alpha-1-released#comment-79839 makes me realize that this is an
 ongoing question and I expect it will come up more with the new Torbutton
 interface for visualizing your paths.

 What should users actually do with the information that, for example,
 their first hop and last hop are both in the US?

 If we have an actual recommendation, we should change Tor to do that thing
 automatically.

 I think the current situation is that there are many attacks and
 adversaries that Tor is trying to defend against at once, and constraining
 paths has surprising trickle-down effects on the other attacks (e.g. if I
 see where you exit then I know where you *didn't* enter, thus reducing
 your entropy, sometimes by a surprising amount depending on what path
 constraints we pick).

 So the current advice amounts to "don't mess with it, you'll probably
 screw it up, we don't understand it very well either". We should figure
 out a way to concisely give people all the intuition that we have, so they
 can make good decisions.
