Or else you have to be really really bad at acting, and then there'll be less of a chance that you intentionally misrepresent yourself online. Who you think you are may or may not reflect who you actually are- more likely it reflects the qualities you see as the most vital to your "you-ness." But if you're actively promoting these qualities, it's probably at the sacrifice of all those subconscious characteristics that you present throughout your day. I can try to paint a decent picture of myself on Hubski, but the very act of trying to paint the picture makes it less accurate. Might just be that the person least likely to give an accurate representation of you is you. For my part, I wish I was less conscious about how I present myself. I think I'd get my personality across a whole lot clearer that way.
