The way Edgeio works is that bloggers would post items they want to sell right on their blogs, tagging them with the word “listing” (and eventually other descriptive tags). Then, Edgeio will pluck them as it constantly crawls millions of blogs looking for the “listing” tag and index them on Edgeio.com.
It would be interesting to see if this could be a threat to eBay. Instead of going to one central site (eBay) to list your useless junk, just post it on your own site and let Edgeio come to you.
So how will Edgeio make money?
