I pick up marketing books from time to time. (I had blogged about marketing as it relates to the Indie Mac Developer a while ago, when I was reading those kinds of books frequently!) I ran across Platform: Get Noticed in a Noisy World by Michael Hyatt. It has inspired me to try blogging again.
I think that I had lost my blogging mojo when I was active in Twitter (and Facebook) but I've been Facebook-free for over a year now, and I've cut down on Twitter a lot.
Maybe if I feel like saying something, it takes more than 140 characters.
Let's see if this sticks.
