I'm just curious now...
Do you find yourselves camouflaging while here just to ensure someone you know (on the outside) is not able to easily figure you out?
That is: an online (NL) persona and an offline (Real life) persona
It may be in form of ensuring you don't share the same jokes here as you have elsewhere or it could also be taking the extra precaution not to type in the same manner you are known for typing etc...
PS - I'm not by this post referring to identity disorders o.. lol
