The point stands, they make more than just the blonde at that brewery location, and many of the beers they brew are stouts. If you want to fault Visit Baltimore for accidentally posting a nitro rather than a standard stout (although both are served at the location) go ahead, but seems nit-picky to me. Maybe they meant to post the Bourbon Barrel Aged Imperial Stout, or the Gingerbread Spiced Stout, or the Mint Chocolate Stout.

Of course the Guinness Stout is going to have more ratings, it's sold all over the world and has been around for hundreds of years. I don't see your point. By your metrics, many beers brewed in Baltimore are "obscure" when you compare them to Bud Light.

You can also go to the brewery to have a Guinness stout brewed in Ireland, go on a tour of the Baltimore brewery that has historical information about the brewery, and maybe try a brew from the newer location while you're there. I vastly prefer going to many of the breweries within walking distance of me, but I think Guinness is also a great time.
