A little feedback on voice. When someone says "You should stop using them. Now.", I expect the article to be about some system killing security problem, not an argument for the elegance of one tool over another. And if the argument is going to be about elegance, it better be absolutely compelling. The benefit of piped grep expressions is that you don't have to know anything beyond the principles of Unix to intuit their usage. For many uses (most uses for me), no thought is required -- grep fades into the background and becomes part of the programmatic brain stem. Commanding the reader to no longer use it is as effective as telling them to stop breathing.
