I'll admit that I don't have the most exciting looking blog, but I do what I can to spruce it up when I can figure out how. I got rid of the Goodreads bookshelf that was there before (which didn't really work as I'd hoped), and replaced it with a book montage of my 4 and 5 star rated books from Goodreads.
Now you can see all the books that I think are definitely worth reading, with their pretty covers and all! I got the idea from Amanda Hocking's blog.
If you have a blog, what are your favorite design elements that you've added? How did you find them (or how to add them)?
