OkCupid

It is more than a dating tool, you can consider a different social network. Where in addition to knowing you can find the love of your life.
They hold contests and there is also a section of the Blog where they give you suggestions for you to have a good profile.

"On OkCupid, you’re more than just a photo. You have stories to tell, and passions to share, and things to talk about that are more interesting than the weather. Get noticed for who you are, not what you look like. Because you deserve what dating deserves: better." Source:https://www.okcupid.com
