Christopher Sibona, a doctoral candidate at the University of Colorado at Denver’s business school, has a few insights regarding why someone you thought was a good pal dropped you as a “friend” on Facebook. In perhaps the first study exploring why online friendships end, Sibona finds that the top reasons for getting rid of a buddy on Facebook is frequent and unimportant posts, according to a CU-Denver press release highlighting the research, which will be published early next year by the “Hawaii International Conference on System Sciences.”

As Sibona points out, you might want to get over yourself: “The 100th post about your favorite band is no longer interesting.” Listen up, candidates for U.S. Senate: The number two reason for being dumped is rooted in posts about polarizing topics like religion and politics. Number three: writing crude or racist remarks.

But be careful: If a status update at first seems inappropriate—it might say something like, “I like it on the floor,” for instance—get your mind out of the gutter. That particular update is likely part of an effort to raise awareness about breast cancer, and the seemingly improper approach is a trend for the campaign, notes New York Daily News. Is it effective? The New Yorker looks at the difference between strong and weak ties in attempts to organize various causes using social networks like Facebook and Twitter.
