Probably the most talked about site in dating circle is Plentyoffish and no its not because of the fact that this site, run by a single person Markus, is making around half a million dollar per month only from google adsense.
Plentyoffish is discussed for its design, or should I say for its lack of any design. Yes, if you visit this site you will see that its probably one of the worst designed site which is making such huge money. Many webmasters believe that the high earning might be because of the bad design and not inspite of it. According to them visitors are more likely to click on ads when they are on a poorly designed sites. If thats true then I might have to change this blog's design very soon :-(
