The Internet has become a voracious social animal, and Facebook is to blame.
The giant social network taught us to go online and share all kinds of previously personal information with strangers. Now, scores of smaller websites are taking a slice of Facebook’s action, creating communities for people with specific interests, from shared medical conditions to avoiding the next highway speed trap.
Pinterest is a combination bulletin board and search engine, where users can share hobbies ranging from old cars to architecture. Trapster is a community of drivers who swap sightings of police radar setups. Ravelry, a group of knitters, is one of numerous social networks built around a hobby. On PatientsLikeMe, people with similar medical conditions can swap their experiences and symptoms.
