To go along with my general insanity, I subscribe to about 115 blogs on Google Reader, so every week, I have a ton of reviews hitting my feed. If I actually read each one slowly and in detail, I'd probably end up spending more time reading reviews than sleeping.
Instead, I usually only read reviews for books that I'm interested in or that catch my attention, and when I do, I tend to skip the synopsis, skim the body paragraphs, and closely read the conclusion. I find this is the fastest way to glean information about the reviewer's thoughts without losing or getting bogged down by detail.
The only exceptions are when I come across reviews written by bloggers whose opinions I particularly trust. These are essentially people who I've noticed (a) have similar likes/dislikes in books as me and (b) articulate their feelings very well.
How do you guys read reviews? And if you're also bloggers, has it changed the way you write reviews?
