Four years ago—four years ago?—I got an email from a total stranger. He’d read my blog, and wanted to know if I was interested in an internship at a hedge fund company in New York. I didn’t get the internship, but I did decide to move to New York.
I got my first serious job from someone who liked my blog. And the internship that turned into my current position also got started when I submitted a writing sample, which I took straight from the blog.
So I know a thing or two about getting hired based on having a blog. I also know why writing a blog made me waste time, alienate customers, and feel the whole time like I was accomplishing something.
