Those with something to gain.

That might be nothing but pure enjoyment. There's a charm to staking a claim on the horizonless frontier. That might be remuneration. Maybe your clients will find you. That might be expression. Blogs are like diaries that you deliberately leave lying around. I think it starts to unravel when the page owns you - and you have to update it because that's what you do, not because it's fun.

My wife had a blog attached to her professional website because the SEOs will tell you to do that. Wrote articles for it and stuff (and this is a person who has been published more than a few times). What you discover is that if you're not feeding it regularly the "failure to thrive" is evident from a mile away.

And then we didn't worry about it for a while and then we killed the links to it and then you could only get to it if you had the URL and we still found mountains of spam. and a Romanian hacker running a phishing operation off her cPanel, I might add.

My wife wouldn't have a website if she didn't need something for clients to see. I don't. I'd rather my clients call me on the phone.
