I'm looking for what will get me most social media attention. I have a site that provides insurance information, so it would be used by most people, in the footer I'm going to place some social bookmarking possibilities, but I can't make out what to present to the user.
Is it better to just have: Facebook, google and twitter so the user has few and well known options, or would it attract most social media attention if I use AddThis and provide a massive list of social media bookmarking possibilities - what are your thoughts/experiences?
