I just read a book on social media for the author. Okay, honestly, I listened as my Kindle read it to me. I was stunned that there were so many references to John Locke's book HOW I SOLD 1 MILLION EBOOKS IN 5 MONTHS ( http://donovancreed.com/ ). I'd already read John's book, so nothing was new information, but this (very short) eBook seemed as if was trying to capitalize on John Locke's author status. Or something. There was a reference to John's book, with a long passage, then a short page and a half or so elaborating. Not that there weren't some good nuggets, but I'm glad I didn't pay more than 99 cents for it. I'm not going to name the eBook, because it's not worth mentioning.
I did learn a lot from John's book, and I've also learned some great information from Kristen Lamb's book (http://warriorwriters.wordpress.com/). As an author we need to separate ourselves from the masses, and let me tell you, it's a full time job.
I love social media, and I was on Twitter, Facebook, and Blogger long before I was trying to market a book. This made the transition easier, but I have to try really hard not to run off my regular followers/friends with sales pitches. So I only put on the salesman/marketer hat a few days a week. I'd much rather enjoy the media to stay in touch with the "friends" I've made around the world. I just hope those friends my feel compelled to purchase my novel.
