Provide verbal and written feedback to Product Managers on new and existing products
I'd prefer Google to solicit feedback always from more than one publisher (the more, the better). Opinion of a single "representative" may not be so representative (it is very likely to be biased). Only a "modernist" mosaic of views can give them some truthful and useful picture. Hopefully, the subjective opinion of this person (whoever it will be) will not be taken as "what all the publishers want".
