This morning, I went back and started reading one of my stories that I posted 18 years ago(!). It's my most downloaded and highest-rated story, but I was shocked by how many careless errors I found in just the first chapter. I'm thinking of fixing it and reposting, but since it's so successful, I'm not sure its worth the effort.
My excuse is that in those younger days, I sometimes got impatient and didn't spend as much time rewriting before posting as I do now.
