Ask HN: Should we pivot our idea?

We were working on a small startup that helps people to find good restaurants/hotels and give directions to them and give reviews about the locations. This was before Foursqare started focusing more on exploring places and specially on places on food. We've like just got started and still have only handful of users, so there is no chance of competing with foursquare. Should we pivot our idea to something else like event/trip organizing using the locations we have? or what's the good idea to change this in to? Thanks
