For me it is open as well. One of my web sites is my full name. I use Eric G or Bigebiz on all my social stuff and usually add my name as well in a signature.
I knew long ago, that YOUR name is important, and your reputation even more. I have always tried to help as many people as I can and I continue to do so here and their when time permits.
Like the Dr Mani article, and the Grand Poobah Ed himself, I have always taken a personal approach and associate me with Eric Gehler. I guess it could be an ego thing as well, love to see my search stats for my name ( unique as it is) and see how many references their are.
Regardless, the NET is an impersonable thing, bringing a face and a name to it helps build credibility and and the flow of ideas which at times lead to a profit.
Differentiating yourself is a personal preference. I don't feel it should be one way or another. To each their own.
If you feel you need duplicate account then go for it. Some of us have Duplicate accounts to test or promote a product other than ourselves
