I find it useful. It also doens't clog the freq much, since the
tranmission originates on the ground.

That's a pretty weak argument. When I'm in the air approaching an
airport, I'm not listening for folks on the ground (if I can even hear
them), I'm listening for folks in the pattern. When I'm on final, I'm
looking for folks on the runway or runway intersections, and listening
for any departure calls.

I usually don't make taxi calls unless the taxiways are busy. The
exception to this rule is for crossing runways--I always announce my
intention to taxi across a runway, followed by a visual inspection in
both directions, before I cross.

Unfortunately, taxi calls do clog the frequency both on the ground an in
the air, and are usually unnecessary in my opinion.
