Flipping domains

In addition to flipping, domainers have other ways of making money from their investments. Most domainers post ads on their Web sites, which can generate a decent monthly income. And Jackson says more and more domainers are teaming up with Web developers to create their own online businesses.

Then there are even more creative arrangements.

"I've leased a domain to the president of Spain," says Adam Dicker, a domainer who owns DNForum.com, a site where domainers chat about industry trends and sell domains to each other. Dicker says the Spanish premier José Luis Rodríguez Zapatero rented his domain, zp.com, and used it as the homepage for last spring's presidential campaign. Maybe it helped. Rodriquez Zapatero was re-elected. Notes Dicker, "And he paid a good buck."

Kind of misses the point, but the carpenters union in the U.S. is hiring homeless people, retirees and students at $8 an hour to picket, $12 an hour to play buckets.

Mystery eBay auctions getting ridiculous and ridiculously profitable

There are dutch auctions (explained at the site) and then,

The second type of mystery auction involves offering a silly item, such as Cheez Whiz or a 7-year-old hamburger, as the “item”. Then irresistible gifts are implied for winning the auction.

But the bidders just have to hope that the implied gift is cool and worth, say, $3500.

Speeding drivers stay on road by paying others to take the rap

Points are traded for cash on eBay in France. Some are pensioners who haven't driven in years who just need a bit of money:
