I would love for that sentence to be explained. The speaker took the stage and spoke with confidence. I saw no signs of nervousness. As for geeky, I guess you mean he was skinny, wearing a rumpled shirt and glasses? Sensibility? You mean he looked sensitive, or reasonable?

I dunno, it just seems like a whole lot of snap judgment of a guy and some words that seem to have just been assembled at random because it sounded cool.
