This author didn't seem to realize he was reviewing the testnet alpha release of OpenBazaar 2.0 rather than the current 1.0 release that is available for easy download on openbazaar.org.

Since version 2.0 is entirely separate from 1.0 and about to transition from the alpha testnet to the beta livenet, those listings he tried to view are old and don't work anymore. It won't be a problem once beta is officially launched this week and while the effort is appreciated, this review is premature. Users are encouraged to revisit OpenBazaar later this month when the full release of version 2.0 is available!
