Top three myths that you don't know will kill your blog

I love to read blogs that offer practical tips, scan-able lists, and quick advice, and I enjoy writing in a similar style. But there can be too much of a good thing. Inspired by a brief Twitter exchange with @mStonerBlog and @andrewcareaga, I thought I'd share my own top-three list of tired blog memes:

• Things you don't know, have missed, and aren't going to find anywhere else. In this world of information overload, no one wants to miss out on a big story amidst all of the noise.
  
• Things you think you know, but what you know is wrong. Have you been misled by myths? Thankfully, there are blog posts that will clear up the confusion!
  
• Concepts that will kill other concepts, kick other concept's tail, or are dead. Email, Facebook and Google social media projects may seem like living organisms. They might seem threatening at times, or even look like they're being threatened. But they don't have a pulse. They do not have weapons or a physical presence. They cannot fight, receive medical treatment, or be thrown in jail for their transgressions.

P.S. Some might add that top-three (or top five, 10, etc.) lists have also passed their prime. Considering that David Letterman's top-10 list has endured for more than 25 years, I think the theme is immortal.
