Writing yourself vs. hiring a writer

What's your take on writing blog posts for content marketing yourself, vs. hiring an outside writer? For me I used to write everything, but after I found a solid writer a few years ago that started changing, and I probably write less than 10% of CrankWheel's content marketing nowadays (I write everything on my personal blog though). I miss writing more, but it would also be a big time commitment for me on top of everything else. Would love to hear what others think, particularly want to hear from founders who still write everything themselves.
