Now that I am using the paid version of Grammarly, just as an experiment, I get a "report card" each week. Here are the results for the last seven days:
I am more productive than 96% of other users.
I am more accurate than 89% yada, yada.
I use more unique words than 90%, etc. (I bet I know what a lot of those words are).
What all that tells me is that maybe I don't need Grammarly. I'll give it another week, but I'm leaning strongly toward canceling. I figure I've managed to post 40-some-odd stories here before I even heard of it, so I may go back to self-editing. I'm not trying to write the great American novel, or even the so-so American novel, just some dirty stories.
