I took my email out of my profile a long time ago when I found myself spending time thinking about whether or how to respond to the weird, inappropriate emails I got from men. One wrote me a very long email on Christmas about how something I wrote made him want to kill himself because it reminded him of his bitch ex-GF. You said it in your article, but I realized then that I want to be in control of which parts of me I share...and inviting people to spill their responses into my inbox was more than I could handle.
Whenever I see writers who share their emails, I wonder if they've had a more positive experience or if they just feel like they're 'supposed' to share it.
