An ingenious Finnish company, Igglo, has put flesh on the bones of the old adage "everything is for sale at the right price". Quoth Springwise:
"The Finnish company has photographed every building in Helsinki, with more towns to follow, and combines these photographs with satellite images and maps. Every property is listed, not just those that are currently on the market. (Their tagline is: "Your house is already on Igglo.")"
This is essentially the end-point of the digital marketplace - where absolutely everything is listed by a central facilitator and buyers and sellers come together whenever a price can be agreed, quite regardless of the fiction governing whether or not a thing is "for sale". Everything is for sale. (Incidentally it's not clear to me why eBay isn't doing this already in the second-hand merchandise market - I occasionally wonder idly if two million cuecat scanners are still going for thee dimes a pop, and if so whether eBay will ever pick them up and send them to users so as to scan in all their possessions against the possibility of a good enough offer? I might not have been planning to sell my George R R Martin first editions any more than I was planning to sell my house, but there are possibly people out there who would offer me enough to change my mind.)
Possibly a similar model will emerge in recruitment - all CVs and all jobs posted online, and if there's someone out there who'd be better at your job and willing to do it, everyone knows it immediately and you're out. (That's pretty much already the model in professional sports, of course. The difference in the professional sports is cultural - that everyone acknowledges this is the situation - and informational - the market is small enough for everyone to have all the information on both sides.)
And so Igglo. A good start. A taste of things to come in a number of other markets. And a hint of what happens when all of the information can be available to everybody all of the time.
