Lee Odden, a recognized expert in the areas of search and social media, recently ran the 2010 Digital Marketing Poll on the TopRank Online Marketing Blog. The poll, presumably directed at marketers, asks: “What 3 online marketing channels & tactics will you emphasize in 2011?” 
TopRank used Twitter to promote the poll–and did so on multiple occasions. Presumably, a lot of people received notice of the poll: @TopRank has 6061 followers, the update was retweeted 262 times, “liked” by 45, and likely got additional visibility through other social sharing media*.
