From Radiant Digital ~ Bright Ideas in Marketing and Technology: Top 10 Reasons You Need a Sales Blog:

QUOTE

One of the toughest groups to win over when deploying technology has always been the sales force. Let's face it, sales folks are cut from a different mold and everyone has their own "modus operandi."
So why are salespeople a good target for Blogs?

Here's the short list:

1. Information at your fingertips ...

2. You become the de facto destination for information...

3. Better distribution of your content...

4. Instant collaboration ...

5. Branding ...

6. Online Proposals ...

7. Cross-selling opportunities ...

8. Humanizing your company ...

9. So when you're "Googled", you're found...

10. Because your competitor is already using Blogs...

At my last company, we used a Sales Weblog to distribute competitive intelligence, partner/vendor information, and other general updates relevant to closing new business. Blogs are an easy way to digitize the information sales reps use the most. Think about how many times reps look for the latest Powerpoint, Proposal , spec sheet, etc. With a sales blog you have a central repository for the information and anyone can comment on it. That alone is very powerful when you consider the amount of collective knowledge it takes to win a new client. 
And with the RSS feed, reps know when the site is updated. How many intranets can do that?
