Thanks for the shout out Harold. I love this line in your post: "Look at how difficult it is to maintain a clear line between LinkedIn and Facebook contacts." Never a truer word was spoken. Jane Bozarth and I were just discussing this yesterday on Twitter (irony... ; ). I made the point that I never made that separation between personal and professional that you refer to. My Facebook account is now this hodge podge of high school friends, work acquaintances, professional contacts, clients, prospects, and even industry analysts. Needless to say, it's a complete mess... ; ) My professional colleagues don't necessarily want to hear about my diet milestones, and my friends could probably care less about my latest blog posts. And clients are probably not all that interested in my Libertarian political leanings... Did I mention it was a mess?

But I guess that's the point at some level. I'm one of those people who lives at the intersection. I work for Mzinga, but I maintain a lot of external relationships - some with customers, some with industry thought leaders like you and Jay, some with clients and prospects... That's the reality of knowledge workers -- boundaries are blurry and people connect wherever the information trail leads them. Increasingly, corporate "walls" are turning into New England-style stone walls that provide as much value as places for neighbors to meet and connect as they do in demarcating boundaries of "ownership."
