I guess it depends on what is considered a "social network". I canceled my facebook a couple years ago and don't have twitter or instagram or anything else like that. I do however belong to some forums (vbulletin type sites) and pay for some extra perks on them. Like being able to post in the classifieds, etc... I notice that since getting off of facebook I started going back to forums that had specific topics. I find that the discussions on there are much friendly an about a specific topic.
