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.
