Tinder introduces super-like feature. Does this make swiping right a diss?

Dating app adds a third swiping option - the super like - but will users want to know just how eager a suitor is?

In the dating sphere, "treat 'em mean, keep 'em keen" used to be the adage. That, and the "three-day rule" - the length of time it was deemed necessary to wait before contacting someone after the first date.

Tinder, however, has distanced itself from received courting wisdom with the latest addition to its dating app - the "super like" feature, which allows users to declare an interest more eager than a mere swipe right.
