A majority of US social networking users say their fellow users mostly kind, and that the sites make them feel good about themselves.

A Pew Internet survey of some 2,260 American adults found that 85 percent of social networkers see fellow users on sites like Facebook to be mostly kind. Only 5 percent said reporting finding fellow users acting mostly unkind.

Some 68 percent of social networking users surveyed told Pew researchers that their networks have made them feel good about themselves. And 61 percent reported having experiences that made them feel closer to another person, according to Pew.

We're also seeing acts of kindness on our favorite social networking sites.

Pew also reported that 39 percent of those polled said they frequently see acts of generosity by others on their social networks, while another 36 percent said they sometimes see others behaving generously and helpfully.

It's not all social networking roses, though.

According to Pew, a third of those surveyed said they have experienced some "negative outcomes" from being on social networks. And 49 percent said they have seen people act cruelly at least occasionally.
