Ever wonder who drinks what at a cocktail party and why? Jeff MacGurn compares beverage preferences of social media folks to those of search engine marketers after attending the latest MediaPost Social Media Insiders Summit. In a humorous tone, MacGurn tells us he observed that nearly half -- or 45% -- of search marketers preferred beer, compared with 38% of social marketers who like to guzzle the brew. "These socialites also have a slightly higher preference for premium beers than search marketers," he writes. In the post, MacGurn also analyzes the drinking habits of those who enjoy cocktails and wine.
