Post Revisions

With the break looming ahead, and readers looking for more to read, we would like to call attention to the revised, updated and elucidated postings from the past. Following the advice of an anonymous mentor we have strived to make "arguments cleaner, crisper, and better supported by evidence and reason" and have occasionally even added explanatory footnotes! These posts have been marked in the title as "updated" or "revised". Although we have done this for purely altruistic motives, feedback and/or enhancement of grades would be appreciated.
