Sometimes but it happens to the best of us. The thing is that the awareness and self-conscious aspect of what we do post is just that our own. People are rarely going to be that focused on what you write just the impression and tone that you write with. When its got character, its tons better than nothing unless its so bad like some sort of inebriated carcinogenic spike. Depends how comfortable you are in accepting your self in the face of other peoples responses and the errors you see or don't see in what you express. And whether you can deal with what is going on in the new transition of yourself when in reflection or review.
