I often try to articulate why I think blogging has been such a transformative action for me. Seth Godin and Tom Peters have articulated it brilliantly in 1 minute and 37 seconds. They are both marketers, but what they say is relevant to anyone who writes a blog. Watch this.
Then start blogging.

I totally agree with you Jenny – articulate, to the point and on the money!
Bloggin’ is as important as a gas bubble poppin’ forth from a volcanically stimulated mud pool, that is all.
Interesting. I’ve approved your comment, noting that you say on your blog that you approve very few comments. Blogging has certainly changed my perspective on education and the ability of people to have their voice heard. Your perspective may be coloured by what it is you blog about and the audience you attract.
