if I were worrying about my diction I’d be typing proper sentences and use appropriate punctuation. I’m not, however. I am posting to an Internet forum with strangers that don’t know who I am. It took me maybe 2 seconds each to type all my messages. I am not so worried about my composition as I am my soul.
Spork makes a good point.
If you are worried about your soul, you will attempt to do all things well. That includes writing to strangers on internet. It is not a good idea to get into the habit of using sloppy language.
