From Marketing Tom, we have another tidy list of blogging tips:

1. Improve your title tag
2. Read a bunch of blogs before you start
3. Write in a granular style
4. Demonstrate your passion & authority
5. Add comments
6. Make yourself accessible

These tips are originally from Robert Scoble and Shel Israel - all links to the above material can be found via Marketing Tom.

My suggestion - Understand the tips as they are - don’t get bogged down in pages of explanation as to why you should blog or why in a certain way. The tips are valid, but the main point is that you should begin blogging. Be honest, be interesting - your style and your audience will come to you. After you’ve started, learn to refine your strategy.
