I'd sorta promised to tell you-all about my nerdiness, and hadn't yet done so...
SO. "Hello everyone!
My name's Beverly, and I'm a nerd."
My nerdiness is rather concentrated in my love (read obsession) of books. When feeling shy, books are a wonderful camouflage, one actually looks like being alone was planned, instead of unavoidable.
Before the advent of personal computers, browsing encyclopedias was the total joy activity. Find an article on alchemy? I'll absorb it.
Skipping the stories not to my taste still left me scads to choose from.
But now, I find "an exposition of sleep has overcome me"..." And so, good night unto you all."

I would consider myself more of a goober

Reason is my default setting. Everything has a reason and looking for and adopting that premise gets me into all kinds of trouble. Liberals are often as guilty as conservatives for taking a position on a subject and then touting it as the only truth. The nerdy part of me also looks for ideas away from the norm. I love science and am good with math. Being an introvert also adds to ones nerdy status.

I used to do ludosport(competitive lightsaber dueling) I suppose that might classify me as nerdy.

Nerd? I barely rate geek status.

I used to work in the tech industry, and by comparison, I was a pure hedonistic party animal. I did know some extroverted programmers. Yeah, those were the ones who looked at your shoes when they talked to you. And I can't pass up any episode of any show that David Attenborough narrates.

Depends on what you call a nerd. I an not a techie, but intellectual and scientific matters always interest me. I do not keep up with pop culture at all.
