A bunch of people who know my son Justin have asked me what he does for Clearspring Technologies with AddThis in the Washington D.C. area. When I say he's their community manager, they smile and move on in the conversation.
It's a job that seems to have blossomed with the tech industry, but is relevant to most businesses and other organizations.
He loves his job and he really comes alive when explaining their product line and how it can affect life on the web. For his explanation of what he does, check this post in the Tech Cocktail blog where he is interviewed. It's pretty good.
