>The original commenters point still stands though right?
Yes!
> Also isn't addition of salt often a sign the chef/cook messed up and under-salted a dish?
Being a question of taste, literally, it is a subjective question.
IMO you should respect the choice of the chef/cook, and if we are only talking of the "messed up" dishes, then I hope the cook dont mess up that often that is justify to add a salt shaker on the table.
On the other side you have people that add salt to every dish, and this before tasting it, those one are on the dark side!
but real question on the value, IMO this tool is very useful for beginners, but myself being more experienced now, I would not use it.
The html structure and the inline style are not good enough right now.
