Do you read book reviews? Whose do you trust? Do they affect your reading habits? Your buying habits?
I have a strict rule on reading book reviews... I don't. I don't want to color my view of a book by seeing it through another's eyes. However, I do have a ton of book bloggers on my Google Reader. I have found some people who have similar tastes as myself. So, I often use their reading lists as a guide for new books. If they give a book high marks (I try to only look at the rating), I'll add it to my list.
After reading a book, I often go back to certain book bloggers to read the details of their reviews. It's interesting to read what they thought versus my thoughts. Sometimes I comment on their reviews and sometimes I don't.
