I half agree with you.
I accept that the seaweed has good nutritients and mulch wise it is not
great.
However I do think its value as a soil conditioner is invaluable. I
believe the alginates within the seaweed help to reduce the leaching of
nutrients within the soil. This makes sandy soils more retentive and
helps to open up clay soils.
I saw an exhibitor at a green keepers exhibition in Harrogate a couple
of years back, where dried, flaked seaweed had been used on golf
courses to reduce their chemical inputs - to the point where some had
gone organic - very unusual for a golf course.

I have used seaweed meal from the Chase orgainics / HDRA catalogue and
on a couple of alotments and felt it did improve things for me.
