"The Real Value of Tweets" (New Business, Jan. 18, 2010)
"The Real Value of Tweets" (New Business, Jan. 18) contained a mathematical miscalculation that led to erroneous conclusions. Twitter's payments from Google (GOOG) and Microsoft (MSFT) work out to $3.13 per thousand tweets, not 3 cents per thousand. This changes the premise of our story. We regret the error.
