Think about how people will respond to your blog post. Ask why people will talk about it or, better still, why they will write about it.
Why are urban legends viral? They have a sense of incredulity. People can't believe it, it makes them sit up and they want to share it because of how they responded to them.
People love surprises. Remember how the office loved the fact you brought in doughnuts to the weekly meetings. Remember how they grumbled after 2 months that you're bringing doughnuts again to the weekly meetings?
The unexpected doesn't have to be fictional. It can be a piece of knowledge that people feel compelling to share. That is the power of gossip. The delight of communicating something you know that someone else doesn't.
Did you know there are almost 95,000 applications on the iPhone and you can only load 148 of them at any one time?
I'm willing to bet if you read this post, you'll tell someone in the next 24 hours!
Next time you write a blog post, think Boo!
