I LOVE the flavor of seaweed myself... and if they taste like sushi then they must be good. A lot of people don't like sushi and seaweed is foreign to them so they're probably just not used to the flavor/are too afraid to try it. The flavor of seaweed isn't even the overpowering. I guess it must be an acquired taste. Seaweed salad is awesome though (I just had some with sushi earlier today). You should try it if you haven't yet.
