Maybe someday Google will add a feature where you search to find out what brands celebrities are using in real time (or, maybe someday, we'll stop caring).
Until then, we'll have to rely on things like Gawker Stalker and this great post from starbucksgossip.com (I know it's my second link to that site in a row, but I couldn't help myself. I have Starbucks on the brain). The site is harnessing its avid Barista readership to let us know who drinks what. Of course the blog is independent so it doesn't report just good news for Starbucks, or print positive feedback from its Baristas. But it's another example of the cool things that are possible when you have a popular blog tied to your brand.
