New Site for Classified

My Friend created a new website as http://www.mootly.com for classified and check it out. He is coming with quite new concepts for classified which no one has taken so far till now, like craigslist, ebay. He explain me the his concepts, it is mind blowing and surely once implemented fully I sure it blow it other website all-together. I just did the signup on this site and whole process for signup is so cool and buyer can send me email directly from my posting while browsing the listing.
