Well not if you are a writer, or a promoter of writers, the weekend is the best time to connect and be seen. Getting picked up by Google, or selling a book, the weekend is the time to reach out to thousands! Make sure to inject some levity into your posts, and send out your message several times within 24 hours if you are having a promotional event, and send them out to ALL of your social media sites.
Books and articles do better with a picture and a small excerpt, just remember to keep them small enough to be posted within your tweet. Twitter will post a snippet of approximately 550 x 650 and likes .png files better than .jpg files. Facebook will take the link directly from your url, as will LinkedIn and Google+.
