Miscellaneous: Interesting Concept

Here's an interesting concept. Create a marketplace for...whatever. The only condition is that every transaction is to be valued at five dollars. It's called Fiverr.

Fiverr is still in beta, it seems. I had problems--I tried to join, but the site has failed to deliver the confirmation e-mail required to complete registration. So, I can't try this out yet. Still, it seems like a great idea. There are plenty of things I'd happily do for five dollars. What would you do?  Fiverr.

[Update: I eventually found the mail in my spam folder. I've put up my first gigs--offering to answer any wine-related question for $5, and offering to recommend bird watching hotspots in Sonoma County for $5. We'll see if I get any response.]
