Bill Flitter at Pheedo has a great post about the nature of blogs and blogger best practices.
From the post:
1. This is a NOT a medium where a message can be forced.
2. It takes time and attention to effectively reach out and build relationships.
3. Blogging is NOT a direct response medium. It’s a relationship medium.
4. Blogging ROI is NOT measured as a cost-per-lead but as a cost-per-influence.
