If I want to hire a contractor, I will ask my neighbors who they used to have the work done on their house. I am not sure I want to go through some site where people paid to be listed and to be referred to someone who cannot get work based on his reputation in the community, but rather in the online community.
UPDATE: Yelp! seems not to be doing so well these days, either. In a few years, we'll say, "hey, remember online review sites? Sort of like AOL or MySpace...."
"It was all hands on deck obviously at that point, and we put a team in place to focus on that particular cohort and that particular profile,” said Jed Nachman, Yelp’s chief operating officer. “And we’re able to really course-correct in a pretty short period of time and saw progressively better results as we got into March and particularly in April.”Translation from CEO-speak: "We're fucked!"
