OKCupid is a dating site that has attracted attention by analyzing data from its users and publicizing interesting analyses on its blog.  For example,  a lot of traffic to their site came from this article on the profile photos that generated the most responses.

Mr. Yagan and three other Harvard mathematicians founded OkCupid in 2004. In its fight against much bigger competitors like Match.com, PlentyOfFish and eHarmony, it has tried a number of marketing techniques, often with little success. But the blog, which OkCupid started in October, has helped get the company’s name out on other blogs and social networks. A post last month that set out to debunk conventional wisdom about profile pictures brought more than 750,000 visitors to the site and garnered 10,000 new member sign-ups, according to the company.
