Here's the list:
Merlin Mann's 9 Things To Do to Make a Good Blog (Paraphrased)
1. Have a personal voice2. Show your obsessions3. Show where your obsessions take you – the trail of attention, the evolution of your interests. Blogs are an ongoing narrative of this – a story!4. Write in paragraphs: craft, not crap5. Use style and format creatively6. Be weird7. Inspire – make other people want to start their own blog8. Try harder9. Know when to break your own rules
I think #3 might be the most interesting. I'd never quite thought of blogs as being like narratives in that way, before. It's a clever analysis, don't you think?
(Except for #7; it might be true, but it's not useful advice!)
Anyhow – listen up! Based on this list, I have a game for you. A game of death.
No, wait, not a game of death. This is the game: think about how many of these qualities your blog has. If you have 6 or more, you win! If you have all 9, you are lying. How many (& which) would you like to have?
(I'd be happy if I thought my own blog maybe had #1, #4, #6 and #8 so far, but I don't really know; either way, I'm sure I still need to try harder . . . )
Do you agree with the list? What qualities are truly important, do you think?
