Flippid. Hmm…this online buying and selling service could be a real rival for eBay if it gets traction. The idea is that you post stuff for sale, or that you want, and the system matches one to the other. Sounds simple, but the matching technology needs to be pretty clever to make sure that buyers and sellers find each other fast. Once a match has been made you are notified by email and can choose to trade or not. Fees payable on sale (min 10c).

Why’s it interesting? Because it lets you set a product and price and forget it until sold or located, no worrying about auctions, sniping, renewals etc. It’s Ajaxy, taggy and has a feedback system so all the boxes are ticked, but of course the big problem is that it needs users, so let’s see how it goes.

 Every time a flippid user buys or sells something on flippid, they get to rate the participating user based on their experience. They choose from 1 to 5 stars (5 being the best experience possible) and write a small description of the transaction. These ratings go on to form the way the usernames are displayed on the flippid website.
