You might want to categorize this one under mindless fun online. Paird is an online dating site that enables you to take part in matchmaking by simply visiting the site and matching men to women or women to men. Though mindless fun, you might be actually helping someone get hooked up with a date online. As a Paird user, if you are "paired" up with someone else online you get a chance to thumbs up or thumbs down the pairing.
You play matchmaker without registering for Paird but upon registering you can recieve points for solid matches which reminds me of similar dating site ImInLikeWithYou.com. You can also lose points for matches that are denied by the suitor. Though a fun little dating experiment, I don't know yet if Paird is sticky enough to bring me back time and time again.
