I don't even agree that we ALL edit ourselves. 1st. off, that's a sum-all fallacy that you are "assuming" applies to everyone, all the time. It surely does not.
I can assure you, KrisL, in my case, at this particular place in my life, where I can see quite clearly into yesterday.......I can review my career personna....and walk back over old roads.....I am who I have always been and who I will more than likely, always be.
I do not "present" myself online, or any where else in this Universe other than MYSELF. When I'm genuinely happy, which is most of the time, I'm simply happy. When I'm unhappy.....it would not occur to me to paint on a phony "happy" face, or hold up a forced attitude. I'm not at all religious, never have been, never will be. I am, however highly spiritual and in tune with all Universal spirituality, and I hold this as a private piece of myself. Tell me, is it even POSSIBLE to "present" beliefs one does not posess? Let's HOPE not.
I use sarcasm in a lot of my humor.....and I also use it when angry and need to put someone directly in their place....yet, do not want to be blatantly nasty and rude. Sarcasm comes in handy, as long as the recepient is intelligent enough to get the drift.
I may have gone the long route.....but in answer to your question.......THERE is NO difference. I'm "me".....here, there, online, offline......everywhere.
You know, I just realized, .....this is quite similar to the last line in my "Bio." "Like me or not, I'm not changing, because being me has worked well thus far!!!"
