PITTSBURGH -- Twitter users choose the microblogs they follow, but that doesn't mean they always like what they get. Researchers at Carnegie Mellon University, the Massachusetts Institute of Technology and the Georgia Institute of Technology found that users say only a little more than a third of the tweets they receive are worthwhile.
Other tweets are either so-so or, in one out of four cases, not worth reading at all.
Twitter says more than 200 million tweets are sent each day, yet most users get little feedback about the messages they send besides occasional retweets by followers, or when followers opt to stop following them.
"If we understood what is worth reading and why, we might design better tools for presenting and filtering content, as well as help people understand the expectations of other users," said Paul André, a post-doctoral fellow in Carnegie Mellon's Human-Computer Interaction Institute and lead author of the study.
He and his colleagues — Michael Bernstein and Kurt Luther, doctoral students at MIT and Georgia Tech, respectively — created a website, "Who Gives a Tweet?" to collect reader evaluations of tweets. They will present their findings Feb. 13 at the Association for Computing Machinery's Conference on Computer Supported Cooperative Work in Seattle.
People who visited the "Who Gives a Tweet" site were promised feedback on their tweets if they agreed to anonymously rate tweets by Twitter users they already were following. Over a period of 19 days in late 2010 and early 2011, 1,443 visitors to the site rated 43,738 tweets from the accounts of 21,014 Twitter users they followed.
Overall, the readers liked just 36 percent of the tweets and disliked 25 percent. Another 39 percent elicited no strong opinion.
"A well received tweet is not all that common," Bernstein said. "A significant amount of content is considered not worth reading, for a variety of reasons." Despite the social nature of Twitter, tweets that were part of someone else's conversation, or updates around current mood or activity were the most strongly disliked. On the other hand, tweets that included questions to followers, information sharing and self-promotion (such as links to content the writer had created) were more often liked.
The researchers acknowledge, however, that the study participants were not fully representative of Twitter users. Most were referred to the study by technology-focused friends and websites and could be categorized as "informers," who value sharing links and content. Other studies have suggested a schism among users, with others favoring the social "me" aspects of social media.
"Our research is just a first step at understanding value on Twitter," Luther said. "Other groups within Twitter may value different types of tweets for entirely different reasons."
Nevertheless, the analysis confirms some conventional wisdom and suggests nine lessons for improving tweet content:
André, who began the research with his collaborators while studying at the University of Southampton, said it may be possible to develop applications that can learn a user's preferences and filter out unwanted content. Or apps might display some information differently; location check-ins are unpopular tweets, but might be valued if plotted on maps.
But it's also possible that users are willing to tolerate unwanted content, he added. Some people may follow others out of social obligation. Others may dislike certain types of tweets, but value them in the aggregate as helping them keep track of people or issues.
"Social media technologies such as Twitter pose questions regarding privacy, etiquette and tensions between sharing and self-presentation, as well as content," André said. "Continued exploration of these areas is needed for us to improve the online experience."
