I would say "yes, definitely" but whether you should is another matter. Take me for example. I am fairly open and honest around here and can express myself fairly well. You would not recognize me in person because I would be the silent one in the corner. In RL I can't talk. I can see how one part of someone's personality can come out in texting or in the virtual world and that part doesn't show itself in real life, but I'd be wary. That part exists regardless of whether it is being shown at the moment or not.
