Social Apps Summary 

Apart from Facebook, popular and growing social networks and apps were built with a specialization in mind: LinkedIn is where people go for industry news, to look for a job and to network. Path, which was started by a former Facebook employee, is a place to share high quality photos and communicate with a more intimate community. Instagram, which Facebook now owns, is for sharing photos with arty filters. Snapchat allows users to share and annotate photos and videos for short periods of time. Even WhatsApp, the hugely popular messaging service, is a Facebook competitor.
