From the Common Craft blog:
1. Write what you know. Everyone is an expert in a small number of things.
2. Listen. The mythology of blogging is about putting things into the world, but the other part of that is hearing the world- listening. Listen, then write. If you run out to the world with your message without listening, you have a good chance of being wrong.
3. Link often. You owe it to your readers to link to others. Doing lots of linking is likely the single best way to get readers.
4. Post often. Like many things, the way to get good is to practice, plus more posts means more readers.
5. Correct yourself. Bloggers are different when we’re wrong, we can undo the damage when we publish. We can react in a way that makes it better.
6. Generalize. Almost everything starts more general and moves to specific.
7. Flame judiciously. One of the things that gives conversation flavor is anger. He sees no reason not to share your feelings. Reasonable people never change the world.
8. Spell-check. The quality matters, though Marc Canter disagrees, so does Jeremy Wright.
9. Look good.
10. Balance hubris and humility- arrogance smells- it stinks and drives readers away.
11. Be Brief. It’s hard to write a short entry
12. Be intense. A cool, dispassionate narrow tone, almost never works.
13. Don’t tell secrets. The blogosphere is not a million writers, it’s a million listeners. If you post something secretive, people will know, like high school- except the web never forgets.
14. Don’t ruin your life. There are a lot of ways you can get in trouble. The question is, why is the media writing about people getting fired for blogging? Think they are worried?
15. Don’t blog on command. People shouldn’t be pushed to blog. The people that should blog will blog.
16. Late add: Be sincere
17. Late add: Never Lie
18. Late add: Write for pleasure
