I have been writing my writing, gaming and game-design oriented blog
Designer's Notebook since 2003.
Still, having a Goodreads blog focusing solely on matters of writing and reading... maybe it is not impossible to do. I am currently collecting feedback on The Hollow Pilgrim and waiting to see if my publisher wants a sequel. Because if they don't want it, I already have some contacts who will. :)
The book is well-liked, if not particularly well-sold. I'd like to see some more reviews in social media or here at goodreads but I guess ebook releases don't really get that kind of attention?
