I also remember the day I was done with it. It was a clear and fairly clean break.

Sorry, should've added to the original post... Yes, me too. I called it off when it was no longer fun, when I realized that most of what I was doing was what I was also doing for my day job. The very last straw came when I saw a story I'd rejected turn up in another zine--utterly unedited. And that zine won a fannish award. WTF? So yeah, all the trouble I was going to to winnow out 'bad' stories, and edit good ones? What a waste. I was done.
