The Writer. I'd had a subscription previously, and when I moved back to Florida, I got it again. I thought, if nothing else, it will keep me motivated to keep moving forward in my writing.
I value this subscription. Not only do I look forward to getting each issue, but I read them, and keep the back issues to refer to later. I have a whole stack of magazines on my (make-shift, temporary because we're in the process of moving) desk.
One of the things I like about The Writer is that it gives a wide variety of information. Even if the overall theme of the issue doesn't really apply to me, I can find something that helps my writing.
Besides the encouragement and inspiration that comes from the magazine, it makes good sense from a career standpoint to read The Writer and other writer-focused magazines. (Writer's Digest is another good one.) For writers, the magazines can be considered trade magazines. They give information about news and insight into the industry, helping writers become better writers and advancing careers.
No matter what industry you're in, it's important to keep learning and stay on top of advancements in your field. Even though the publishing industry has remained largely unchanged since its inception (though e-books and the rise of self-publishing is changing that in recent years), writers should keep learning and reading and growing to be better writers.
The Writer is one way I can do that. Reading fiction (and non-fiction) is another way. I love that I have to read to improve the work I do.
How do you keep up with publishing/writing news?
