Some Q's for David:

However I think there are a few 800lb gorillas in this space, such as the venture backed http://gdgt.com – do you think they are a direct competitor or at least in your vicinity?

Monetization plans – anything past affiliate stuff?

What will get the user to keep coming back? I've noticed with gdgt.com that these types of sites are ones that I visit about once a month to update my profile (add stuff I own or want), see what people I follow are adding to their inventory.. and that's about it. Nothing too high priority from what I can see. That being said gdgt does try to redeem itself with product-centric forums/threads which end up becoming a support forum of sorts.
