Or, you know, correct it anyway. Because when someone’s making themselves look like a moron, may as well call as much attention to it as possible. Maybe then they’ll be a little less apt to sloppy laziness. :p

I only do it for glaring errors, though. People using apostrophes to make plurals, the standard “your/you’re” switches and such, “loose/lose”, and so forth. Then there’s lack of caps and d00d shorthand ( ur/u/ne1 and so on )
