The invasiveness is definitely a concern - but in my experience things that quiz you on preferences are rarely actually accurate. Honestly I'm not normally so liberal with sharing my location data, knowing actual people who work there probably tilted this in their favor. I'm not an expert in recommendation systems or anything, but just anecdotally it seems like the amount of real observed data needed to make actually accurate recommendations is pretty high, beyond the abilities of a short intro quiz. Though having experience building apps one concern is self-reporting vs. observation. Foursquare knows every place I go, not just the ones that deserve a pic on Facebook or a checkin. The problem with asking users for their top restaurants is that the responses you get will be more aspirational than real, and reflect who the user wants to be rather than their actual preferences. > " but those would still end up factored into your recommendations with Foursquare" On the history page you can mark places as "not liked", presumably this lessens or removes the impact of it. Definitely still some user interaction required - but it's IMO still a lot better than manually checking in, or using a completely unintelligent system.
