Think long term adjustment to the mentality of the site. If that link was worth something, why would the buyer just give it away? It's possible that the buyer would try to sell it and compete with the original seller, and all subsequent buyer might follow, but that would be something the original seller could take into account in pricing their product.
I agree that the link shortening aspect of this site cannot be it's product. Emphasizing that at all can detract from the truly novel idea that exists in selling and buying micro-properties of internet knowledge. People need to see the incredible nature of a site which allows you to sell information which has high demand and low supply, but has no other method of paid distribution. For everything too small to put in a book, and not small enough to just give away. I think its brilliant.
