Thanks to SF Signal, I came across this interesting post on The Guardian Book Blog. Once again, it's about whether or not one can trust online book reviews.
Here's an excerpt:
"But why should we believe the blogger?" comes the cry. "Who are they and how are they qualified to tell us what to read?" The answer is: you should believe them and trust them in exactly the same way you would a critic in a newspaper or literary journal. There will be some you admire and some you think are stupid. Some bloggers write well and some badly and so do some literary critics.
