You only have one corporate blog!?
Anil Dash thinks that a business need more than one blog. See what happened to email. Our email (ab)use started out as one address per company. Then each department wanted one and today, of course, everyone has an email address or more. We are also on a number of email distribution lists.
Already, writes Dash, there are "...universities that deploy Movable Type across their entire institution admitting students who just expect to have a blog in the same way they expect an email address. Today, many businesses may be content with just having a single blog to talk to the public or for tracking projects and work inside the company. But we think that a lot of people who've seen how easy and effective it is to use blogs to share information with the audiences they care about will start to demand blogs for every audience they want to reach."
I'm sure that the email analogy can be questioned. But Dash is probably right anyway. In fact, back in April I wrote about the Dutch company Macaw where all employees had a blog. And many of them used it to. Since then we've learned about IBM's offer to all employees to start an intranet blog.
There's guaranteed more examples like this -- and even more will come.
