Books Go Social is strong in author support. Some of their ideas are solids, like posting your book link for anyone who wants to review it (not swapping reviews). I'm not too keen on liking fan pages and having them like me back because authors liking other author pages doesn't really do a thing for your readership. It only makes you LOOK popular. The only thing I dislike is the volume of emails I get from FB alerting me to the volume of posts. I've tried turning them off to no avail since I commented on one of the more popular posts. I finally had to create a rule in my Outlook to shunt them to another folder.
