Twitter: a stand-in for opinion polls?

Check out this CNN story about a study by Carnegie Melon University indicating that “sentiments expressed via the millions of daily tweets strongly correlate with well-established public opinion polls, such as the Index of Consumer Sentiment (ICS) and Gallup polls.”

The full report of the study hasn’t been released yet, but it’s interesting to think that the twitter comments about a city or other government agency might be a reasonable representation of the views on an issue.
