You said your boss said that your "good at engaging people in work conversation" then what more could he ask for. I've worked in jobs where I was a "public servant" (courthouse/police station) and the community loved me...I am very socialable etc.
BUT I do not believe that work is a place to come and vent about your life, kids, what your doing this weekend. I am not close to any of more co-workers, I do not chit chat with them, I come in do my job and leave. I know a couple of them think I should be more sociable at work but seriously why would I want to talk to them about my life??? I don't think social skills are important just for your co-workers to like you...as long as your doing your job and pleasing customers who cares about co-workers
