While I find the negative BBB rating of Zinni interesting, the other
two links don't move me too much.
When you have self-reporting, in this sort of review forum, you have a
"self-selecting sample." In other words, two kinds of customers
typically respond: the very happy and the very unhappy. It's not at
all randomized and, therefore, of minimal value. I know this based on
professional experience in the area.
What's needed is proactive survey data, usually conducted by a BizRate
or a vendor providing such surveys on behalf of the retailer.
Outbound calls reach a randomized sample, and--over large enough
sample sizes--tend to get the feedback of more than just the outliers.
Good to know, though, that Uncle Otie is hawking for a company that
the BBB characterizes as "unsatisfactory." I have to wonder if he has
some economic benefit from his constant referrals.....
