Last month I wrote about the first Facebook app marketplace. This weekend, a new one launched which has duplicated the eBay auction platform technology called Appmrkt. As of now there are only 5 applications that are for sale but I have a feeling this will grow.

I find it particularly remarkable how the Facebook economy has rapidly become a self supporting ecosystem. From Facebook developers, to consultants, to development tools, to online auctions for applications and finally the risk seeking investors. This has truly become an incredible ecosystem that I am proud to be a part of. The Facebook economy is thriving and the launch of this marketplace is a symbol of the success.

If you want to buy or sell Facebook applications, go check out the Facebook AppMrkt.
