Beware of zombie rules

Some people still stick to rules like these:

• A sentence can’t start with the conjunction “and,” “but” or “or.”
• “Between” shouldn’t be used with more than two people or objects.
• Don’t use “over” to mean “more than.” Use “over” only for the spatial.
• Never use “while” to mean “although.”
• “Who” refers only to people and “that” only to animals and objects.

But these are false rules, often still taught as absolute must-follows. Such rules are called zombie rules, I recently discovered. See this article from The Baltimore Sun for a list of other zombie rules.
