I like the letter x. You hardly see the letter x anywhere. I'd like to humbly suggest we, as a society, start using the x to pluralize words. This would lead to several advantages. First, this would solve the whole issue of whether to use just an apostrophe or an apostrophe-s when making a plural word possessive. Secondly, it would lead to more x in our writing, which is good, because x is the coolest looking of all the letters.
