Foursquare Splits To Take On Yelp
InformationWeek reports that check-in app Foursquare is splitting into two pieces. One of them -- the part that will retain the Foursquare name -- is actually losing the original check-in functionality, in favor of local reviews and recommendations; a second app called Swarm will get the who's-where-right-now part of the Foursquare functionality. From the article: "Foursquare isn't the first company to unbundle its features into new apps. Last month, Facebook announced that it will separate in-app messaging from its official iOS and Android apps and require users to download Messenger to chat with friends. Users will have two weeks to download Messenger before the service in the main Facebook app disappears, the company said. ... Foursquare's changes also aim to capitalize on a mobile app trend: Taking online friendships offline to meet up in person. Most recently, Facebook announced its opt-in Nearby Friends feature, which will display your friends' locations on a map and track, store, and share your location with others." -
The Math of Gamification
An anonymous reader writes "The Foursquare blog has an interesting post about some of the math they use to evaluate and verify the massive amount of user-generated data that enters their database. They need to figure out the likelihood that any given datapoint accurately represents reality, so they've worked out a complicated formula that will minimize abuse. Quoting: 'By choosing the points based on a user's accuracy, we can intelligently accrue certainty about a proposed update and stop the voting process as soon as the math guarantees the required certainty. ... The parameters are automatically trained and can adapt to changes in the behavior of the userbase. No more long meetings debating how many points to grant to a narrow use case. So far, we've taken a very user-centric view of p-sub-k (this is the accuracy of user k). But we can go well beyond that. For example, p-sub-k could be "the accuracy of user k's vote given that they have been to the venue three times before and work nearby." These clauses can be arbitrarily complicated and estimated from a (logistic) regression of the honeypot performance. The point is that these changes will be based on data and not subjective judgments of how many "points" a user or situation should get." -
Type Safety Coming To DB Queries
An anonymous reader writes "A new type-safe query language for the popular full-text search platform Solr, called Slashem (a Rogue-like), has just been released. Slashem is implemented as a domain-specific language in Scala, providing compile time type-safety, allowing you do things like date range queries against date fields but keeping you from trying to do a date range query against a string field. Hopefully this trend catches on, resulting in fewer invalid queries exploding at runtime." -
Foursquare Turns Down $100M
theodp writes "Valleywag is stupefied that 'an annoying, unprofitable social network like Foursquare would turn down $100 million,' a move inspired in part by Twitter's 2008 rejection of a $500 million offer from Facebook, which in turn once rejected a $900 million bid from Yahoo. Time will tell whether the move by Foursquare was a prescient one, but it's certainly gutsy. After all, today's $850 million company can prove to be tomorrow's worthless one, right AOL?"
