Just as eBay made it possible to trade from within the comfort of your own home, Yardsellr makes it possible to trade from within the comfort of their social network.

I just bought a dog sweater from a stranger who lives across the country from me. And I totally blame Yardsellr, a year-old startup backed by a team of eBay veterans who may well be inventing the future of social commerce

Bringing social commerce to Facebook is a big opportunity attracting a lot of capital these days

Yardsellr says it uses social plumbing to power all interactions between buyers and sellers, although users create listings and consummate transactions.
