This post touches on your question, Lori: http://jarche.com/2013/03/only-open-systems-are-effective-for-knowledge-sharing/

In the network era, we can keep our personal lives private, but we have to know that anything can become public at some time. Almost all of my social media activities are done in public. However, I once lost a client due to something I wrote on another blog, so it can have repercussions. Even in that case I realized that the client was not worth my time and effort, due to their restrictive practices.
