Seth Godin thinks you should blog and I agree.  What better way to reach your world?

What should you blog about? What is that people ask you for advice about? 

The thought of having to write a post once a day or even once a week can seem pretty overwhelming…but if there’s something that you feel compelled to say…even just one thing…start with that.  And then, as you learn more…improve it.

So why not give it a try.  I’ll save you a lot of time researching blogging platforms and recommend TypePad.  I’ve been using it since 2004 and every serious blogger I know uses it.
