Tom, when I read the title of your post, I thought you were investing in a walker for your old age.
With all due respect to Rajat Parr, the folks at RN74 and Peggy Hirsch (among, I'm sure, many others), any organization that publishes a "manifesto" to justify and explain their existence is already a bit too serious for me.
Though laudable in concept---c'mon, who doesn't like balance, outside of those sensualist lawyerly types who want explicit, forthright statements of fruit and people who put cigars on the same level as wine?---I don't think this is going to be a break out group with wild success.
I think a campaign of "Save the Pinot Noir" (much less "Save the Chardonnay") is going to resonate sufficiently with anything beyond a precious few (emphasis on precious). And even though I'm inherently sympathetic to the view of these folk, I don't feel the need to climb the ramparts: I'm pleased that some winemakers, and sommeliers, and consumers champion a certain style of wine they prefer, but I'm afraid the laissez faire market doesn't care as much as they do.
The call for "make the pinot noir the way I like it, dammit" is not nearly as loud as "I'm making pinot noir that sells just fine, thank you very much." in our vast and unwashed marketplace.
