Jane, to be simply honest it's both for me (we-centered as you put it).  I'm all about transparency, authenticity and being "me" and won't be apologetic about the fact that I use social media for personal branding and marketing and networking -- but I also share valuable content from others in leadership, marketing and business, and I generate awareness about causes close to my heart like domestic violence and violence against women prevention.  And parenting quips being a father of two girls.
