An interesting discussion has broken out between Revlayer and ExpoTV. Both presented at last week’s Web2NewYork networking party.

Revlayer’s founder Allen Stern at CenterNetworks questions whether the filtering policy of video review site ExpoTV is ethical. At the W2NY meetup ExpoTV’s Thi Luu had said they let retailers pick what they show.

‘That just does not sit well with me,’ Stern wrote on his blog.

Thi Luu responded there are practical reasons to leave it up to retailers. ‘Video is a new medium for most retailers and comparison shopping engines,’ Luu wrote. ‘They haven’t yet been able to build into their sites the sorting functionality about the content being positive or negative.’

ExpoTV’s CEO Daphne Kwon added: ‘All of our syndication partners publish all of our video reviews – positive and negative – for all products and that we have never been asked by any of our partners for even the data required to publish only positive reviews.’

I’m not going to take sides in this one.
