Both is true for me. I also am more "myself" in the internet. I could not imagine to make so much words in a row in real life or talk about my feelings, thoughts and opinion so much. Apart from internet, as far as my opinion is demanded, I will say what everyone else said so that I don't draw attention on myself and don't make a fool out of myself. I am able to chat with one single person at a time if I know them for a while and am relatively sure they don't reject me. I'd never do a group chat.
