All of these tools allow you to at least manage more than 3 social networks, most of them allow you to engage or manage in Twitter, Facebook, LinkedIn, and Google+. The more robust ones add in Instagram, Pinterest, Weebo, and other similar networks.
We also included a few tools in here that are mobile only (which is a new and emerging space). As usual with all of our ultimate lists, we’ll keep this updated as we find new tools and platforms.
