> When did using "+" instead of "&" become acceptable in proper English? I understand this is a tech blog and I have no problem with "+" used in a tech context, the use in a virtue signalling piece on the rules of writing a good essay seems misplaced. Could be that tech bias. I've been coding awhile, and '+' reads as 'ADD', for inclusion, while '&' reads as 'logical AND', for restrictive subsetting. The '&' no longer sits right. (Plus, it's a shell and HTML metacharacter, thus it's a potential potent piece of trouble in casual typing and so something to be avoided.)
