Trover, which quietly launched earlier this month, takes some of Color’s most basic ideas and puts them into an easy to use free iOS app (iTunes link). The app is based around the idea that you want to share photos of cool places around you with the rest of the world. There is also a location-based social networking aspect to the app, but you could easily ignore this aspect of the service without losing it’s basic functionality.
When it comes to social search and social recommendations today, there is a lot of hype around the concept, but given that a user’s social graph is – almost by default – limited, there are major gaps in both accuracy and coverage when it comes to putting this concept into reality. While Google +1 and Bing’s implementation of Facebook ‘like’ data are trying to find ways around this, Microsoft researcher Mohammad Raza argues (PDF) that we need a smarter recommendation system that is based on the idea that “your friends know you and can best predict your taste” and that social search can be greatly improved upon with the help of prediction extraction.
Facebook today announced a number of new features for Facebook Groups. Group admins, for example, can now pre-approve members and Groups now also feature a Q&A and photo-sharing section. More importantly, though, Facebook also introduced a new new button that publishers can put on their site: the Send button. This button is a close relative to the Like button, but with the added twist that it allows users to selectively share a webpage with one of their Facebook Groups or email it to their friends.
Facebook co-founder and CEO Mark Zuckerberg just told a group of aspiring entrepreneurs at Y Combinator’s Startup School that he expects to invest most of the money Facebook is currently making back into the business. According to him, it currently “doesn’t make sense to make a massive profit,” as Facebook is already able to provide the necessary incentives to keep and motivate its employees.
Apple just released a new version of iTunes for Mac and PC that makes some much-needed changes to how the company integrates its social network Ping into the application. Until now, not only was Ping somewhat hidden in iTunes, but you could also only really interact with it from within the iTunes store and not from within your iTunes library. Unless your friends are compulsive music shoppers, chances are that few of them ever went through the store to mark their favorite songs. Now, however, in the new version of iTunes (10.0.1), you can very easily like songs right from within your music library and you can choose to see a sidebar with the latest activity from your Ping friends while browsing your library. Chances are that this will raise the activity level on Ping, though it remains to be seen if this will be a dramatic change.
