I wonder how much eBay has been impacted by this type of "wedging". I would use eBay primarily to buy/sell musical instruments but Reverb took a pretty big chunk of that market and provides a better and more trustworthy experience than eBay, at least in my experiences there. I know there are a few fashion-related sites like this out there and I'd guess there are other "Reverb for X" sites as well. I'm sure there is still a fortune in the long-tail but specialty sites seem to be more of a concern than a direct competitor.
