I only have a single, global persona. It's why my username for various sites is either 'dana' (my first name) or 'diederich' (my last name), with very few exceptions.
I've been using the Internet almost daily since 1988, and for the first 8 or 9 years, I embraced being pseudo-anonymous. I really can't say why, it was just what everybody was doing. If all of the online activity of all of my different personas was mixed in public, it would have been no big deal.
Having said that, I understand and respect that, I presume, most people need to be able to maintain different personas.

While I certainly don't say exactly the same kinds of things to everyone, everywhere, I do generally act the same in every situation.
And I think that's kind of unusual.
Feel free to ask any clarifying questions if you like.
