Yesterday's announcement by Facebook about their new messaging service, dubbed Facebook Messages, proves one thing — that social is still about people.
Despite all the advancements in technology; the connections between services; the ability to create content on the fly; and, the how easy it is to get the info we, as consumers want, social remains to be centered around people.
Services like Facebook, Twitter, LinkedIn, MySpace, Foursquare, Yelp, etc. connect people with people. Yes, people are connecting because of content, but at the end of the day, it's the relationships that we forge via these channels that really matter.
