Comment (by starlight):

 Replying to [comment:6 mikeperry]:
 > circuit formation and client usage is even more visible when there is
 not relay traffic involved

 Agreed, no doubt w/r/t pure-client operation.

 I have two thoughts:

 1) in general, if two configurations or implementations
 exist, x1 and x2 where x2 is more anonymous than x1,
 one should prefer x2

 2) some consider it a reasonable idea to configure a client
 and relay in the same daemon instance with the belief
 that this would obfuscate local client traffic to some
 degree; but with the implementation as it presently
 stands such an idea is false and should be denigrated
