Good question.
Both mainly due to Seth Godin, I know I am not the first to say it but the guy is good!
My friend pointed out to me recently that Seth's books are pretty much just an accumulation of his posts.
It seems like it must be pretty easy for him when it comes to compiling his thoughts so I thought I would try and do the same to keep my options open in the future for writing etc.
So why typepad?
I only have one blog feeding to my Inbox (Seth's blog), it always works well, I enjoy the layout and I trust the guy that writes it. So I copied him, Typepad must be the best.
Thats the power of Seth's "Trust brand".
This is the first of many, I hope you enjoy them, let me know if you don't why not.
