I'll tell you what's interesting. This blog. It's from a fairly unsexy uptime monitoring company, whose services I've got little interest in. If the blog was just company updates ("we've got a new server" or "20% off all packages this week") it'd get very little traffic. But I've got it in my RSS reader and it hits the social news sites every other day with well-written and often humorous observations on tech.

Lots of people have heard of Pingdom who ordinarily wouldn't; it just goes to show how a little effort making your website something more than just a corporate website can go a long way.
