No wonder I was not able to find newly opened restaurants and some local spots which were available before the auto-update.

- loceng 12y agoFacebook doesn't seem to measure for quality, they just seem to measure for quantity..
- antr 12y agoFWIW, Foursquare data in Europe is not very good, I think FB geo data is better. I've mentioned this before on HN, Foursquare in Europe is quite unreliable, with places appearing way off the real location, badly categorised (e.g. a restaurant categorised as a bar), etc. I guess quality on these services depends where you are.
- ZenPro 12y agoI am curious how this can be possible? Does FB and Foursquare utilise broadly similar geo-location technology from within the mobile device? Not saying you are incorrect - just wondering if a technical expert could elaborate on the accuracy.
- maxerickson 12y agoThey buy different starting data sets. I guess most services also use things like the free GNIS data set from the U.S. government (it has good coverage, but the geocoding is not amazing). Edit: And an entity like GNIS actually has less resources than Foursquare gets with its army of users (or at least, a lot less feedback generation).
- pbreit 12y agoProbably more of a human thing than technical. The accuracy benefits from crowd-sourcing and Foursquare is used relatively significantly more in the US.
