I adore using em dashes, they're just too useful. I read a *lot*, often trying to follow the reading flow that I think™ the author wrote in their head. That means pausing in certain moments, w/commas, em dashes, or even speeding up. An em dash has other uses too, but in many ways it's just a comma that isn't a comma; it has a bigger visual impact on the reader, it can segment run-along sentence incredibly well, & also it's just fun to use :P
I've come a fair way since I started writing (not that you'd think it going off of my profile here lol, most goes unposted or the very least on alts) & em dashes are onna the things I've come to embrace & love in that time~~
