Shilling is a crappy part of being a writer. Or publisher even, since I technically qualify as that too. I really hate doing it, and when I do shill I try to do it in respectful, non-spammy ways.
I also make no money as a writer and even less as a publisher. So there are obviously some flaws to how I market.
Still, nothing turns me off more than strangers randomly trying to mass network with me. I wouldn’t even think I was worth shmoozing, but it does happen once in a blue moon. (A friend and I were approached after we were on a panel at a tiny convention by someone who wanted to press their business card on us. I had no idea what to do.) Even my tiny little zine, Mad Scientist Journal, gets a bit of spamming from people who don’t know me but want to team up or something.
