The Thrill of a Good Review

Having just received a very nice review for GO HOME AND DIE, my Vietnam-era mystery e-book, I got to wondering about reviews and reviewers. (You can read it at http://ahistoryofromance.wordpress.
com/reviews/patricia-pellicane-reviews/go-home-and-die/ and it's available on Amazon. or at Red Rose Publishing)
My first book got hardly any reviews. My second, HER HIGHNESS' FIRST MURDER, got lots, and it was a big boost for me as an author to know that reviewers were interested enough to choose the book from the hundreds available to them and then pleased enough to review it positively.
So my questions are these: As readers, do you pay attention to who does the reviewing? Do you read reviews randomly or only in the genre you prefer from a source you trust, like PW? Or do you find an individual reviewer you trust and pay attention to his/her recommendations?
For my own part, I never paid much attention to reviews until I met P.J. Coldren, but I've come to appreciate the talent it takes to review fairly and well. It isn't just "I liked it a lot." or "It stinks." At
least, it shouldn't be!
