Sometimes I just need to modify my writing a bit, sometimes I delete the whole thing. Sometimes I put the posting on the back-burner if I'm not sure how I feel and then delete it.
I have never published a post without carefully reviewing it at least one day later. Untold damage can be done by not getting the whole story or a proper perspective. Posting knee jerk reactions can do more harm than good. Look at Twitter, peppered with stories of mindless posting without thinking about the consequences.
Although this blog is mine it does affect those around me. Other people, though rarely mentioned directly or indirectly, are often the subject or the cause of my postings and should they read them, it could do more harm than good.
This is definitely a place for me to post my thoughts but it still requires at least a little etiquette. And I am, if nothing else, tactful.
