this one is really suseptible to someone adding all his/her friends just to see who they match - once you delete someone, the other person is no longer notified of the crush. plus, multiple people can match (downside) and there's only one type of relationship (the crush). and there aren't many fb connect sites out there: this is a good example of one.
