I have failed at finding a writer's critique group that suits my needs.
My first one was a collection of beginners , so it was the blind leading the blind.
After I had several published books I outgrew that one and tried some others. Sometimes I was the only one who knew anything about the publishing world, so the group wasn't helping me grow and they were ignoring me anyway, so I quietly dropped out.
In others, it was all fiction novel writers and I was writing nonfiction -- mostly biographies. I definitely didn't fit.
Now I'm writing mostly picture books and yes, also biographies. So - should I join a picture book group or a nonfiction group? (there are few to no nonfiction groups.)
The two of us nonfiction writers in the large Baltimore writer's association would often cling together, especially because we were published and most everyone else there weren't.
The very best writer's group I ever belonged to wasn't a critique group at all. It was a group of published Maryland writers who met an hour away from where I lived, but the conversation was great! (It was an hour and a half if I was coming from my workplace, but I still attended when I could.)
