Blind Man's Puff is a good resource. All reviews are blind, none of the reviewers know what they're smoking until the review is posted, so there's no bias. I used to review for them, haven't in a while. But a good group.

I love cigar reviews, especially for new smokes, but I don't follow any one reviewer. Instead, I go looking for a consensus among reviewers, like a self-compiled Rotten Tomatoes for cigars. Mostly I look to see what everyone is tasting, and take away a general idea of the cigar's flavor profile and performance as a guide to determine if I should pursue sampling that cigar or not.
