I just engaged a local class company who’s Yelp reviews were atrocious. The reason was, 3 of the 4 were reviews of the guy’s driving, not his skills at changing a windshield. I went to FB, and saw reviews with pics of work and overwhelmingly positive scores. Gave him my business. Though, I did think about it a bit before hand. Also thought about Yelp’s relevance and the value of the very recent reviews that were all not for his work, but his driving.
