Some notes :<p>OKCupid co-founder Christian Rudder wrote, "Those who seek to deny love and instead enforce misery, shame, and frustration are our enemies, and we wish them nothing but failure."<p>However, instead of simply posting the letter on the company blog, Rudder made sure that every person who visited the site from Firefox saw the letter, by using the browser's User Agent to redirect them to the letter before allowing them to continue with their heart-felt intentions. Browsers have broadcasted their User Agent, which is basically the browser make and model, since the mid-1990s.
