MTV's new reality TV show Catfish -- which depicts the first meeting of couples who have dated online but have never met face to face -- has people talking about the creepy side of online dating (many of the Catfish stars turn out to be imposters in one way or another).

Creepy or not, the fact is that one in five couples meet online and a form of dating that used to carry a heavy stigma -- has been normalized. Need proof? Google Zeitgeist -- the search engine's annual online presentation of the year's top "trending" and "most searched" terms -- includes a list of the top 10 most searched dating sites, which a Google spokesperson provided to The Huffington Post in an email. Check out the list below, and let us know in the comments if any of the rankings surprised you.
