In reply to toad:
It's a useful tool for two things.
It's great for corporate communications. If you have stakeholders, or if you are or see yourself as a stakeholder, then it's good for keeping in touch.
If you are one of the seemingly infinite number of internet-enabled monkeys who would like to believe that your worthless opinions count for something and that you think mistakenly that you aren't just screaming them into a void of never-ending emptiness, then it's a good way of fooling yourself.
Otherwise, can't see the point.
