You know, there are things to worry about, and things not to worry about, and unless you are printing a book, whether or not people use 1 or 2 spaces after a period really isn't something you need to worry about.
I was taught to add two spaces after a period, and I have no plans to stop doing so. If people really want to complain, I suppose I can show them the latest edition of the APA style guide, which made two spaces the recommendation again, or MLA, which suggests one but notes that "as a practical matter, however, there is nothing wrong with using two spaces after concluding punctuation marks".
Of course, maybe the author isn't as dumb as he sounds... He found a way to get paid to complain about spacing, after all.
