The biggest difference between me online and me IRL is that I 'talk' more here- IRL most people know next to nothing personal about me- only the superficial stuff. I think that is because here I have anonymity and can open up and not feel so vulnerable (altho I only post about 1/4 of what I write anyway lol). . Try not to over-analyse. Just carry on doing what you are doing- that IS you, and you are just adapting to the situation (IRL or on-line) in your own way (IMO).
