If you're a resume writer who blogs, you need to read this article by Gary Korisko:
The Guilt-Free Guide to Earning an Honest Buck From Your Blog
It's long, but completely worth the read, especially this paragraph:
I don't want to scare you, but as someone who has been blogging for 7 years, there will be times when you're writing just for you. People are reading, but not commenting. But the good news is, those posts will be there when someone discovers you for the first time. But you need to be there for them, even when they're not there for you.
But if you go for extremely long stretches of time without blogging (because some other part of your life -- or your resume writing business, even -- needs you), you may have a hard time keeping your audience.
So read the entire post (yes, the whole thing) ... and take his advice to heart.
