Aside from being nearly definitely proof that no good .com domain names are available at reasonable prices, Fiverr, is a very interesting and possibly addictive web site which enables people to buy and sell services -- as long as they cost $5.
Fiverr is the brainchild of Shai Wininger and Micha Kaufman. They seem to have hit on one of the really annoying things about buying and selling services online, the enormous time and effort it can take to make a simple transaction. With fixed-fee predefined transactions, the process could be a lot more efficient.
I signed up today and bought six services, for a grand total of $30. None of the vendors have yet replied, but I'll post back about how they do next week.
Check it out, it's an interesting system.
