Usually, editing is done for clarity. However, the omission of NS seems more like censoring, but that is illogical as people like me would still read your article at your blog.

I learned it too when they published my letters some years ago. My English is quite poor and I am happy that they edit it for me, and from then on, I read published letters with the perception that these are edited versions w/o any proof reading by the writer.

And even many more years ago, I learned that news reports were far from accurate and some time incorrect. They have a tight deadline to meet!

They may provide different perspectives to news, some though may be biased and objectionable, but they simulate thinking among readers. They offer another route of seeing the same news from the blogger’s perspective.
