Plentyoffish.com is Canada’s biggest dating web site and the biggest site in the world run by 1 person. Plentyoffish is similar to Graigslist, it’s not as commercial or profitable as it could be. It is also like Graigslist in the web 1.0 styled site. One of the reasons of the sites huge success is because of “word of mouth”. The average person is in contact with 400 people that they know and feel comfortable referring sites, products and other things to. So if 1 person out of every 100 users tells 15% of their friends about the site and 5% of the friends go there. That can seriously add up after a while. Not to mention the link baits of 900k checks and National News coverage.
