The 3 C's of Blogging

Yesterday I captured on video my comments on blogging for a "coming soon" website. In my need to be concise (1-minute time limit), I compiled the 3 top level concepts I think you need to consider before commencing a blog. Coincidentally all three steps had a "C" adjective that corresponded nicely.

1. Content - What does your audience want to read from you?
2. Commitment - Set the expectation for how frequently you can realistically manage to add new content.
3. Community - Engage with other bloggers, comment on their posts, reference them in your blog, etc.

What else do you think could be added to the compilation?
