I wrote, just a few days ago, that Starbucks' ubiquity and presence is not so damaging as some make it out to be, and in fact, may be beneficial. My argument is best summed up with an old saying: A rising tide lifts all boats. And while truisms frequently are not, there is relevant wisdom in this case.
But good, bad, or indifferent (as if anyone with an interest in coffee could be) feelings aside, there is no denying that Starbucks is a major player in the food service realm, a titan that so eclipses the coffee category that it scarcely belongs in it.
I could tell you why I think that is; but my opinions are merely that, and crafted from well outside the relevant sphere. To read more educated opinion on Starbucks' return to prominence (dominance?), see this blog on Forbes.
