I've been on GoodReads for about a year and just discovered LibraryThing. What are some good ways to use those sites to enhance and promote my blog? Now that I blog, I find I really don't have time to be active on GR and LT (I also work full time). But I don't want to ignore a great resource and could really use new readers. These sites seem like a great resource for bloggers if I knew how to use them. Thanks for your suggestions!
