Anyway, I found out from Flippa's blog that stockphoto.com sold for $250,000 - domain only, no site.
The guy who bought it has now been talking about his purchase. So I guess the story is worth retelling again, as now he's actually put a site up on the domain.
As you might guess, it's a stock photo site, albeit a small one (e.g. no photos of Thailand).
Has the guy wasted his money? How many stock photos will he have to sell to break into profit? It reminds me of 2012 when I wanted to buy a domain through GoDaddy auctions. But it would have cost me $1890. Then I had a brainwave and found out the plural form of the name was available for $10. Fast forward a year and my site with the cheap domain name is doing OK.
