I am currently at MozCamp Asia in Singapore and just gave a quick presentation on blogging comparing a good technical blog post to rock songs. When you think about it, they have a lot in common:

• No intro – just straight to the point
• Memorable hooks and riffs
• One message per post
• Simple language
• An easily repeatable main message (something to scream along to no matter how drunk)
• A memorable solo to end with

Confused? I guess it will all get clearer when you see the slides and listen to the screencast.
