Well Gorwingel is me
In real life I am a terrible writer (which is quite strange because I do frequent a forum where I am required to write), I am extremely shy, and I do enjoy talking about LOTR. I think though in real life I do tend to like to talk more about the films. So I guess you could say that my online persona is a wannabe Tolkien philosopher (which I am most definitely not).
The great thing though about the Internet is that you can check your posts (which much of the time I do not), and you also don't have to pronounce the names of the characters. I think sometimes when I do mispronounce one of their names people think I am an idiot.
But then I also highly doubt that if you saw me walk down the street you would immediately think that I was a Tolkien fan. I tend to go incognito in a way, and I don't even go in costume to the conventions.
So in life I am the way I am in this forum. I am the quiet person in the back that occasionally pipes up, occasionally embarrasses themselves, but is always polite and well behaved.
