I’m familiar with Joanna Penn and would agree, she has a very good site for authors and I just checked out K.M. Weiland – what a wonderful site! I’m actually quite jealous such a young thing can be so smart, the whipper snapper! The Independent Publishers Mag looks good too. Just two more the check out – Catherine Ryan Howard, and the Book Shelf Muse. If you’re a writer, I’d recommend giving these folks a once-over.
