Calendar, statistical tyranny
OK, here’s the disclaimer, otherwise known as the small print at the bottom. Many factors influ-ence what’s clicked into at These include search engines; links from other sites; cross references to pieces in Control Engineering print editions and online; email newslet-ters; our own top 10 and top 5 lists compiled monthly on our home page, department pages, and in newsletters; and RSS feeds. Also, timing has something to do with it. If an article’s posted mid-month, “hits” are split across two months, so one posted early in a month can have more time for “hits.” Whatever the influences, these are great subjects and worth time to read, or read again.
