So lets toss that around here, too.....just why ARE the rudders on the back
of boats?

A rudder is basically a brake. If you apply the brake on the front of
your boat, the front stops while the back keeps moving. This can make
for a wild uncontrolled spin-out.

OTOH, If you apply the brakes on the rear, your craft tends to be
stable. It's that simple.

Anyone ever experimented with a front-rudder?

I regularly sail backwards to get away from the dock, which is kind of
like having a rudder on the front. Leading with the rudder is
inherently unstable, although with a bit of practice it's no big deal.
The problem is once the boat turns a certain amount in the wrong
direction, no amount of steering will correct the problem - the boat
just continues to pivot about the rudder until you've done a full 180.

Because the pointy end sticks in a dart board much easier than that
feathers. I used to play darts competitively and I think in all the
tournaments and leagues I played in I only saw one person using darts with
feathers. I rarely play much anymore but I've still got about five sets of
darts. Darts have gone high-tech. All but one of the sets I have use a
tungsten barrel. The shafts are mostly aluminum but I've got a few nylon
shafts. Feathers are no longer used and have been replaced with plastic or
foil "flights" that come in a variety of shapes and in every color or
graphic on them imaginable. I've got both plastic tip and steel tip darts.
The steel tip darts have a retractable tip and moves slightly on impact
which significantly decreases the number of darts which bounce off a wire.
