Make it manageable
If you've researched the conversations well enough, you'll likely find that there's no need to be maintaining a profile on every social media site available. I'm going to make the assumption that you've enough to do in your business, not to be spending hours on end composing status updates, sourcing images, and generally being interesting on Facebook, Twitter, LinkedIn, Google+, Pinterest, Instagram, AND many others. Making your efforts sustainable and consistent is more important than trying to be everywhere at once. Choose a few outposts, and focus on the quality of your connections thereon.
