Gallup, Inc., is an American research-based, global performance-management consulting company. Founded by George Gallup in 1935, the company became known for its public opinion polls conducted in several countries. From 1936 to 2008, Gallup Polls correctly predicted the winner of the presidential election with the notable exceptions of the 1948 Thomas Dewey-Harry S. Truman election, where nearly all pollsters predicted a Dewey victory (which also led to the infamous Dewey Defeats Truman headline), and 1976, when they inaccurately projected a slim victory by Gerald Ford over Jimmy Carter. For the 2008 U.S. presidential election, Gallup correctly predicted the winner, but was rated 17th out of 23 polling organizations in terms of the precision of its pre-election polls relative to the final results.[15] In 2012, Gallup's final election survey had Mitt Romney at 49% and Barack Obama at 48%, compared to the final election results showing Obama with 51.1% to Romney's 47.2%.[16] Poll analyst Nate Silver found that Gallup's results were the least accurate of the 23 major polling firms Silver analyzed, having the highest incorrect average of being 7.2 points away from the final result.[17] Frank Newport, the editor-in-chief of Gallup, responded to the criticism by stating that Gallup simply makes an estimate of the national popular vote rather than predicting the winner and that their final poll was within the statistical margin of error. Newport also criticized analysts such as Silver who aggregate and analyze other people's polls, stating that "It’s much easier, cheaper, and mostly less risky to focus on aggregating and analyzing others’ polls."[18] In 2012, poll analyst Mark Blumenthal criticized Gallup for a slight but routine under-weighting of black and Hispanic Americans that led to an approximately 2% shift of support away from Barack Obama. At the same time, Blumenthal commended Gallup for its "admirable commitment to transparency" and suggested that other polling firms disclose their raw data and methodologies.[19] In 2013, the accuracy of Gallup polling on religious faith was questioned.[20] Gallup's polling on religiosity in the U.S. has produced results somewhat different[21][22] from other studies on religious issues, including a 2012 study by the Pew Research Center, which found that those who lack a religious affiliation were a fast-growing demographic group in the U.S.[23] Source: *****

I thought that this would be a great site- but after reading about the unwelcome calls and then reading the terms of it's privacy policy it needed a markdown. The worst part is if people make the mistake of using social media with it they  rummage through EVERYTHING!
