Whereas I couldn't care less about the gamification aspects of it.

I use it to read tips about places I visit, which are often useful especially when deciding what to order upon first visit.

I use the social features among a small group of friends. Facebook has similar features but is useless for me as I rarely use facebook, and I am very sensitive about who can see my check-ins. Being a separate social network allows me to curate that list very carefully.

Plus the lifelogging aspect has proven itself useful many times. When you want to remember that awesome meatball restaurant in Amsterdam, nothing beats looking at a list of places you've actually visited. (https://foursquare.com/meatballsnl)
