For some reason I rarely go to Yelp for reviews. I usually come to Chowhound and one reason is I am comfortable with the arrangement of the site and, more importantly, I have read enough posting of some of the contributors in Austin that I have an idea of what to expect based on my history with them on the site (does that make any sense?).
Recently, as you know, Yelp is coming under fire for manipulating reviews based on the businesses giving Yelp their business. Yelp denies this and the truth is yet to be ascertained. But, there is one thing certain that makes me favor Chowhound over Yelp and that is that Yelp does not allow businesses to rebut negative reviews. I am presuming Chowhound has no such restrictive policy. This fact alone makes me wonder somewhat about the credibility of Yelp. I think such a policy lends itself to competitors, or unsatisfied customers, ganging up on a place without the business being able to post a defense. I believe that position to be untenable and if I were a business I would not advertise on their site because of that. Tripadvisor allows rebuttals and many times the dissatisfied party has not told the whole story, or told what the hotel, or whatever, did to try to rectify the problem. .
Too bad for Yelp.
