Thank god I did because that's how I met my boyfriend of almost a year!
Anthony and I lived in the same area, but somehow never met. Tinder changed that, it introduced us and the rest was history!
Tinder shows you how far away the person is from you, if you have any mutual friends and let's you all write small bios describing yourself. You swipe right or left depending if you're interested based on their bio and if they swiped right on you as well then you guys are 'matched'.
One of the neat things about OkCupid the ability to answer questions about your preferences. You answer what you prefer and you also answer what you would want a potential partner to prefer. With this data from all users, the site is able to calculate a "match percentage" for you and every other member. The users who have a low match percentage to you have opposing beliefs, it makes it easy to focus on people with higher match percentages - people you'll have better connections with.
You do have to give it time. I was a member of OkCupid for 3 years and received messages almost daily, all from people who weren't the right fit. But finally I did meet someone who was a great match, and 4 years later we're now happily married!
It also allows you to filter your email so you receive the men who match your criteria search in one mailbox and the men who don't fit your exact parameters in another mailbox. This is a fantastic tool, so you aren't wasting your time reading through 50 emails only to find that half of them live in another state!!
