Now what's the next writing advice to discuss? People who say semi-colons are bad but don't know how to use them?

I'm just always afraid I'll use a semi-colon at the wrong time, so I end up never using them. 

Kind of like an em dash. It's a versatile tool—Some would say too versatile—which is why I seldom use them.  Mostly it doesn't serve any real unique purpose that other forms of punctuation can't handle. There's no button for it either, so you have to go Alt + NUM 0151 which I can't remember and then I spend all this time googling stuff and at the end I'm just like why botherrrrrrrr.
