Read/WriteWeb is pondering what websites are worth. It starts off comparing Plentyoffish, the Canadian dating site, with Facebook. By the numbers? Facebook will have about 15 times Plentyoffish's $10 million in revenues this year. So shouldn't it be worth one-fifteenth as much as Facebook, or $1 billion?

Nonsense. Plentyoffish's founder Markus Frind should be glad his site is doing so well, and that he doesn't have to share his company with investors — or, for that matter, employees, since he runs it by himself. Read/WriteWeb dives deep into an argument about which site has better click-through rates. But that entirely misses the point. Facebook has to find a way to grow into its $15 billion valuation — a daunting task, even as its user rolls swell by more than a million a week. Frind doesn't have to do anything but rake in the cash his site generates.

Maybe, possibly, he could find a venture capitalist willing to write a check that makes him a billionaire — and then, only on paper. But what would he need VC money for? Being cash-flow positive means never having to say you're sorry. There's a simple reason why Plentyoffish hasn't garnered more attention: Silicon Valley is only interested in stories it can grab a piece of.
