Researchers at Carnegie Mellon, MIT and Georgia Tech joined forces to get a sense of how most tweets go over. They created a website called Who Gives a Tweet? that was sort of like a Hot or Not for tweets: Users were promised feedback on their tweets if they agreed to anonymously rate tweets for people they already follow.Over 19 days in December and January, 1,443 visitors to the site rated 43,738 tweets from 2,014 accounts.The verdict? Respondents liked 36% of the tweets, disliked 25% and ranked their reaction to the remaining 39% as neutral. “A well-received tweet is not all that common,” Michael Bernstein, a doctoral student at MIT who worked on the project, wrote in a blog post. “A significant amount of content is considered not worth reading, for a variety of reasons.”
