Yes, I agree, the title is clear;

I point this out because in every conversation about new receptor sites for taste, I see questions about what new flavors or experiences the "discovery" could create - which is (probably) not the _direction_ that implications from this discovery will flow.

For example, MSG was first "discovered" (more correctly, synthesized) in 1908 but the receptor sites (such as mGlu4) were not identified until much later. Glutamic acid was already being added to tons of foodstuff (kombu, mushrooms, stock, gravy, etc) even if the compound and reasoning was unknown. Isolating the compound "making stuff taste good" came before determining the receptor site.
