I've been playing around in there recently, and wow. I mean, wow. There is so much you can do there that it's not even funny. I got in today and started tackling some of the stuff there in hopes of doing some more of the items on my marketing checklist (it's huge btw) and I did manage to get some things knocked out over at Goodreads. But then I ended up adding back an equal amount of things I could do, and THEN some. lol. My list of things I could and should do at goodreads actually made my list grow even after checking off a number of things. lol. That's just messed up.
But on the flipside, it's actually very, very good.
The more cool ways you have to connect with your readers, the better.
