It is a poor workman who blames his tools
Blog postings and texts, even email (to a smaller extent IMHO) can be excused for failing to "follow the rules." In contrast, this is a professionally produced article for a technically astute audience. However the first draft is created, if the article is to appear in a printed format then the author (in conjunction with a skilled editor) must be held accountable for the quality of the final product. If you want to continue to have interested readers, the least you can do is to respect them enough to turn out a grammatically correct piece.
