"What attracts you to a book blog? What puts you off in a book blog? Do you share personal stuff on your book blog?"
What attracts me to a blog? I love clean, clear blogs that are easy to read and pleasing to the eye with book covers that I strike my eye enough for me to want to check it out. I also like to read more than just reviews. I like blogs to be fun with a variety of bookish posts as well as some personality so that I can get to know the blogger.
What puts me off? Dark, dark colors and too much commotion. I don't like having to search through a bunch of clutter just to find the post. I realize that people love to promote books and authors on their page but I don't like when it is disorganized and all over the place.
Do I share personal stuff: Yes, I do. My blog is about my life and that consists of more than just books. I do this through a few linkup/meme's that are designed to learn more about the person writing the blog. So if a blog reader doesn't like that sort of thing, they can just skip over that post.
