I'm glad 2nd person is not common in fiction. I've read a few and always feel like they're trying to brainwash me with mind control. "You walk through the carnival gates, excited about what's ahead. You think to yourself, maybe you'll get two lobster corn dogs instead of one."
No, Jerry, I'm not excited for that. Not at all.
It think omni can be so difficult to do well. There are stories out there but it's a craft in and of its own. Personally, I try to rotate between 1st/3rd past/present to try and flex my writer muscles, but I'm not ready to venture out. Not for a long story, anyway.
