Hmm, I never thought of myself as hiding behind my screen name. It's just a handle....more like a nickname than anything. My grandmother called me Jay-bird, that was a nickname too. There are folks here who know my given name. These are folks with whom I have some rapport. Primemuscle is kind of a laugh since I am clearly passed my "prime", but it chose it a longtime ago and stuck with it.
More importantly, I think people who hide behind a fake persona on the internet do themselves a disservice. The message they send is that they don't like who they really are, so they have to make up a special personality which they imagine is more impressive. It makes no difference what I call myself, I am exactly the same person in real life as I am on the internet. And yes, I have been known to be long winded at times. Other times, I am very reflective and quiet.
Right now, I am off to the gym for a workout and a short respite from taking care of my wife who is dosing in the chair next to me.
