That's good to know. I try not to be one but a lot of times it just comes out as snarky or crass. I still think it's funny when people on here meet me in person and realize I'm not at all what they had pictured based on my posts. It's like their expecting this screaming, angry and tightly wound drill sergeant and in walks a skinny science geek. Not to say that I won't be just as blunt to someone's face if they are wrong, but it's a lot easier to give the impression of civility in person.
