Why blog?

Probably the most important question anyone would ask is, "why should I blog". There's quite a few reasons. Here's my top six reasons why:

1. Way to get personal with customers
2. Get immediate information to & feedback from customers
3. Tell your side of the story
4. Build authority, credibility (especially with media)
5. Improved search/placement/referrers
6. Crisis communication
