Option for private votes

[David Hilvert]

Has consideration been given to the possibility of offering voters the option
of keeping votes private?  This would still allow a greater 'public' sphere of
decision-making than exists now, while allowing voters to keep their positions
private if desired, obviously simultaneously removing them from the pool of
names to be voted for.

Further options could be conceived, for restricting the visibility of one's
votes to a circle of 'friends' or so, and hence being available to votes from
this group, but even the most basic option of making a position public or
private might be sufficiently useful, and sufficiently easily implemented, as
to perhaps be worthwhile.
