WSJ -- May 23 -- The headquarters of what may be, on a per-capita basis, the busiest, most profitable site on the entire World Wide Web is on the 16th floor of a brand-new Vancouver building with panoramic views of the nearby Canadian Rockies. It happens to be the apartment of Markus Frind, the owner and sole employee of PlentyOfFish.com, a free online dating site and a model for the next generation of Web entrepreneurship.

For the week ended April 28, PlentyOfFish.com was the 96th-busiest Web site in the U.S. (HitWise)
Busy Web sites like these usually require scores of people. Mr. Frind says people often don't believe him when he says PlentyOfFish is all his.
Nielsen/NetRatings says that by some measures, such as the time its members spend on the site, it ranks second after eHarmony.
A few months back, he posted on his blog a picture of a check from Google for nearly $1 million for a two-month period. Google confirmed the check was for real.
Mr. Frind says the site brings in between $5 million and $10 million a year.
Many companies would respond to competitive pressure by hiring someone. Mr. Frind says he has no plans to do so. FULL ARTICLE @ WALL STREET JOURNAL
