OkTrends has an intriguing post about sex compiled from the data from the bazillion interaction data of members of the OkCupid dating site (you can read all 10 interesting statistics), but this one is particularly intriguing: active Twitter users have shorter relationships.
People who use Twitter every day tend to have shorter relationships, and the problem gets worse as a person gets older, according to its analysis of 833,987 OkCupid users. The average relationship for an 18-year-old who uses Twitter is about nine months, while “everybody else” usually has a relationship average of nine-and-a-half months. At age 50, the frequent tweeter has a 15 month-long relationship, while the non-frequent Twitter user stays in a relationship for an average of almost 17 months.
